[Tinyos-help] UARTComm and UART0
Hi, I am trying to connect 2 tmote sky devices over the UART0 expansion pins. I looked at the UARTComm example. It achieves the functionality of communicating to and fro with the PC over the UART1 serial link. Is it possible to modify this to send data over UART0 instead? If not, is there a way to communicate over UART0 to another mote? I implemented a simple send mechanism. But I haven't been able to figure out a way to receive over UART0 via an interrupt/event.

[Tinyos-help] UART0 Rx tmote sky
Hi,
I'm using tmote sky. I want to exchange data between 2 motes over the
UART0 bus of expansion connector. I've connected the 2 grounds
together and connected UART0TX of 1st mote to UART0RX of other mote
and vice versa.
I'm able to use the sample given in
http://www.moteiv.com/community/Boomerang_UART0_Sample to send data
over UART0 keeping in mind shared bus.
But I am unable to receive data at the other mote. I've written code
which handles a rxdone event. But i'm not clear what the error is and
can't find sufficient documentation for the same. I'd be thankful for
some guidance on the code.
Bhavish
The code to receive is as under:
UART0Rx:
configuration UART0Rx {
}
implementation {
components SPC
, LedsC
, new MSP430ResourceUART0C() as ResourceCmdC
, HPLUSART0M
, Main
, UART0RxP
;
Main.StdControl -> UART0RxP;
UART0RxP.ResourceCmd -> ResourceCmdC;
UART0RxP.UartControl -> HPLUSART0M;
UART0RxP.Leds -> LedsC;
}
UART0RxP:
module UART0RxP{
provides{
interface StdControl;
}
uses{
interface ResourceCmd;
interface Leds;
interface HPLUSARTControl as UartControl;
interface HPLUSARTFeedback as UartFeedback;
}
}
implementation{
uint8_t data = 'z';
command result_t StdControl.init(){
return SUCCESS;
}
async event result_t UartFeedback.rxDone(uint8_t rxdata){
call Leds.yellowOn();
call ResourceCmd.release();
}
async event result_t UartFeedback.txDone(){}
event void ResourceCmd.granted(uint8_t rh) {
call UartControl.setClockSource(SSEL_2);
call UartControl.setClockRate(UBR_SMCLK_9600, UMCTL_SMCLK_9600);
call UartControl.enableUARTRx();
if((call UartControl.enableRxIntr())){
call Leds.redOn();
}
if((call UartControl.isUARTrx())){
call Leds.greenOn();
}
while(data != 0x12){
data = call UartControl.rx();
}
}
command result_t StdControl.start(){
call ResourceCmd.request( RESOURCE_NONE );
return SUCCESS;
}
command result_t StdControl.stop(){
return SUCCESS;
}
}

[Tinyos-help] UART0 Feedback
Hi, I'm using the UART0 interface on the expansion connector of the tmote sky to receive data. I'm able to receive data by polling for it. The code is attached. But when I try and use HPLUSARTFeedback interface to receive data via interrupts using rxDone, nothing happens. I'm not sure whether it is possible to use interrupts on the UART0 line. If not, would I2C be more suitable? I'll be thankful for any guidance Bhavish ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] GIO interrupt on tmote sky
Hi, I'm trying to use the GIO0 pin as a hardware interrupt. I read about the mechanism to do this. The archives and documentation says that I have to join the R14 ends together and then I can use it as interrupt. I'm not sure about this method. Also, what interface will I use to generate the interrupts? I'll be very thankful for any ideas/guidance.

[Tinyos-help] TOS_Msg size
Hi,
I've been trying to send a TOS_Msg struct over wires between 2 tmote

TOS_Msg packet that will be transmitted? I will be extremely thankful
for any help on this issue.
To transmit, I am doing the following:
typedef struct{
uint8_t val;
}datanew;
TOS_MsgPtr msg;
body = (datanew*) msg->data;
body->val = 1;
packet = (uint8_t*) msg;
length = sizeof(msg);

call UartControl.tx(packet[sendCount]);
while (! call UartControl.isTxEmpty() ) ;

[Tinyos-help] Basestation-Basestation communication
Hi, I'm trying to communicate between 2 basestations attached to the same host computer. I bound a SerialForwarder to each Basestation. Now, I ran TestSerial with one SerialForwarder as it's packet source and net.tinyos.tools.Listen on the other SerialForwarder. While the BaseStation sending packets over radio toggles the red LED (indicating packets bridged from serial to radio), th other BaseStation doesn't seem to receive anything. Is this because of a Group ID issue? I am able to receive using net.tinyos.tools.Listen on a BaseStation when the other mote is running BlinkToRadio (the BaseStation toggles it's green LED, indicating transfer from radio to serial). Any insights into this would be very helpful. Thanks Bhavish ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Basestation-Basestation communication
Hi, I solved my problem. I was setting the AM packet size to be 34 in one mote and sending 34 bytes and leaving the default 28 on the other. Thus the other mote drops all packets it receives. I am testing mote-mote communication over wireless and thus did a loopback.

[Tinyos-help] USB UART capacity
Hi, I am trying to ascertain the maximum rate at which packets can be sent from mote to PC via USB. I'm using the tinyos-2.0 BaseStation app on both the sender mote and receiver mote. At the sender, I'm using TestSerial to send packets via USB to the mote in a loop without any sleep in between successive sends and without the ACK mechanism in Packetizer.java. Given that the mote to PC UART communication is "best effort", I would expect the number of packets transferred to the PC to be equal to the number of packets incoming from the radio at the receiver. But the number of packets received on the PC (using the Listen app) is less than the number of packets sent. What is the bottleneck in this case? I would really appreciate any ideas. Thanks, Bhavish ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] Re: USB UART capacity
I also tried using TestSerialBandwidth. I commented out the code in TestSerial.java which sends packets to mote. Thus, I'm only sending packets to the PC from mote. Using the "as fast as possible" mode, I can send packets at the rate of approx 100Hz in the direction mote to PC. What limits the rate from being higher?

[Tinyos-help] Basestation app
Hi, I'm sending AM packets to a mote from a PC via USB at a rate of 20 ms with data payload = 33 bytes. I've disabled the ack mechanism in the PC to mote USB transfer. But only a fraction of the packets I send reach the mote (I am incrementing a counter in the UartReceive.receive event). On the other hand, if I comment out the "post radiosendtask()", all packets I send from the PC reach the mote. Is the radio send api call taking more than 20 ms to send out 33 bytes of data? A simple back-of-envelope calculation using the data rate of 250kbits/sec over the radio shows that a packet of 33 bytes should take 1 ms to send out. I'd really appreciate any help on this issue.

[Tinyos-help] CC2420 Send interface
Hi, I have to send packets over the CC2420 radio on tmote sky at a fast rate. I tried using the "AMSend" interface but this takes roughly 15ms per packet. I have not been able to figure out the reason for this high value. One possible reason could be that the AMSend addresses the packets so it might take a lot of overhead. There is an alternate "Send" interface which sends without addressing. But I couldn't find any component implementing it. Does anyone know the reason for this high value of time taken per packet or which component implements the "Send" interface for CC2420 radio?

[Tinyos-help] Disable backoff CC2420 tmote sky
Hi,
I too tried the same solution for disabling backoffs i.e. setting the
value of the events initialBackoff and congestionbackoff to 0 and 1 in
CC2420RadioM. But it did not make any perceivable difference in the
time taken for a packet to be transmitted (the time difference between
the send call and sendDone signal). This time was 6 ms before and
after turning off backoff.
Is there something I missed in this procedure?

Re: [Tinyos-help] Disable backoff CC2420 tmote sky
Hi David,
Thanks for your reply. I managed to remove both the initial and
congestion backoff by editing the CC2420RadioM.nc file and replacing
signals to MacBackoff.initialBackoff() and
MacBackoff.congestionBackoff() by the value 0.

[Tinyos-help] Not able to send on radio via GenericComm.SendMsg
Hi,
I'm trying to bridge packets from serial to radio in tinyos1. I'm able
to send packets to the mote via UART. I'm also able to use the
GenericComm component and SendMsg interface to send radio packets. But
when I try to club the 2 functionalities, i.e. send the packet
received by UART signalled by the interface UartTokenReceive over the
radio using SendMsg implemented by GenericComm, the send command
doesn't go through. Infact, the UartTokenReceive event is also not
signalled when the radio send functionality is added.
Is this because the GenericComm and FramerM components can't be used
simultaneously? I just can't figure out the problem and it would be
great if somebody can help me out.
The code is:
#include "UARTMsg.h"
#include "RADIOMsg.h"
module PCToMoteRadioM{
provides interface StdControl;
uses{
interface Leds;
interface StdControl as UARTControl;
interface StdControl as RadioControl;
interface BareSendMsg as UARTSend;
interface ReceiveMsg as UARTReceive;
interface TokenReceiveMsg as UARTTokenReceive;
interface SendMsg;
}
}
implementation{
struct UARTMsg * pc_msg;
RadioMsg * mote_radio;
TOS_Msg to_radio;
command result_t StdControl.init() {
call UARTControl.init();
call Leds.init();
return SUCCESS;
}
command result_t StdControl.start() {
call UARTControl.start();
return SUCCESS;
}
command result_t StdControl.stop() {
call UARTControl.stop();
return SUCCESS;
}
event TOS_MsgPtr UARTReceive.receive(TOS_MsgPtr Msg) {
call Leds.set(2);
return Msg;
}
event TOS_MsgPtr UARTTokenReceive.receive(TOS_MsgPtr Msg, uint8_t
Token) {
call Leds.set(1);
/*pc_msg = (struct UARTMsg *) Msg->data;
mote_radio = (RadioMsg *) to_radio.data;
mote_radio->count = pc_msg->count;
if(call SendMsg.send(TOS_BCAST_ADDR, sizeof(RadioMsg),
&to_radio) == SUCCESS){
call Leds.set(pc_msg->count);
}*/
return Msg;
}
event result_t UARTSend.sendDone(TOS_MsgPtr msg, result_t success) {
return SUCCESS;
}
event result_t SendMsg.sendDone(TOS_MsgPtr msg, result_t success){
return success;
}
}
--
#include "UARTMsg.h"
#include "RadioMsg.h"
configuration PCToMoteRadioC{
}
implementation{
components Main, PCToMoteRadioM, FramerM, UART, LedsC, GenericComm;

Re: [Tinyos-help] Not able to send on radio via GenericComm.SendMsg
Thanks for the reply Michael. I looked at the TOSBase application. The
difference was in the Makefile. I had to add a line: "SP = REMOVE"
Although my problem is solved, I don't have any idea what this line
does in the Makefile!
Cheers,
Bhavish

[Tinyos-help] UART send timing
Hi, I am doing an experiment in tinyos 1 to determine the time taken for a packet to be sent over the UART link to the PC i.e. the time difference between UARTSend.send() call and the signalling of sendDone event. This time comes out to be on an average 7 ms. Since there is no backoff like in the case of transmission over radio, this seems to be a very high value. Is there a specific reason for this? Does the underlying UART protocol wait for ACKs for each packet sent on it? The UARTSend interface is wired to FramerM as in TOSBase.

[Tinyos-help] TOSComm error
Hi, I am using boomerang on windows. I had been using the java serial-pc connection perfectly well and transferring packets to and fro. But I modified the Packetizer.java a little and did a make clean and make in the packet/ directory. I also recompiled the Packetizer.java file. After this, I'm not able to send any packets on the serial link and I get an error saying: Error on [EMAIL PROTECTED]:57600: java.io.IOException: Could not open COM14: TOSComm JNI library runtime error: Error 2. The system cannot find the file specified. in NativeSerialPort.CreateFile I'm simply running the net.tinyos.tools.Listen app and exporting the MOTECOM variable properly. The changes in Packetizer.java were not significant and I tried to undo them but the problem still persists. I even tried running the tos-install-jni as mentioned in a previous post. But that didn't help either. I'd be thankful for any pointers.

[Tinyos-help] UART communication PC->Mote using Packetizer.java
Hi, I'm trying to send packets from the PC to a mote over UART. I need to do this at a rate of 50pkts/sec i.e. a packet every 20ms. I wrote a java code which uses the net.tinyos.packet and net.tinyos.message libraries. The highest rate I'm able to get is around 20 packets/sec i.e. 50ms per packet. I assumed this is due to some ACK mechanism in the layers below Packetizer.java since I commented out the ACK loop in writeSourcePacket() in Packetizer.java. Is there any documentation available which deals with the UART communication details and the java implementation on the PC side? I looked around but could not find anything specific.

Re: [Tinyos-help] TOSComm error
Hi, Thanks for the help. I've solved the problem by the not so elegant but effective technique of backing up my data and reinstalling boomerang :). Anyways, I tried solving the issue and would like to point out a couple of things: - Cygwin uses COM* naming. /dev/tty* would be used on unix. - I don't think there was an error due to the high COM numbers because I was still able to program the mote. - The java file that Urs attached did not give any error on my system.

[Tinyos-help] TOS_Msg length
Hi, I'm trying to ascertain the length of a TOS_Msg variable I've typecasted to a self-defined struct. The struct I use has 6 variables of 4 bytes each. Thus, the total length of the TOS_Msg variable should be 24 + 10(headers) = 34. But the length is shown to be 46. I'm confused as to how this is so. I'd be thankful for help on this.

[Tinyos-help] MAX packet size for Listen.java
Hi, I'm sending packets from mote to PC via UART and using the Listen.java app to print out the packet. I am sending an AM packet with data length (excluding headers etc.) of 44 bytes by modifying the -DTOSH_DATA_LENGTH flag in the makefile. But the packet is not output in the Listen.java app. On the other hand, if I send a packet with size less than the default, it is output in the Listen.java app. Is there an upper limit to the max. size the Listen.java app reads? And can that be changed like the DTOSH_DATA_LENGTH flag is changed?

[Tinyos-help] HPLUSARTControl transmit timing
Hi, I've connected 2 tmotes over the UART) expansion connector and am sending AM packets from one to the other. I'm using the HPLUSARTControl interface provided by HPLUSART0M to do this. The transmit function in this interface is byte by byte. So I have to send the entire AM packet byte by byte. I transmit one byte and then go into a busy wait till HPLUSARTControl .isTxEmpty() returns true. After this I send the next byte. The time taken for each byte to be transferred is around 1.2 ms (and for the whole AM packet is about 55 ms). This seems to be a very high value for transfer over wire. I analyzed it a bit further and found that the isTxEmpty() returns true after approx. 1.2 ms for each byte. Is there a way to reduce this time? Also, is there no event signaled when transmission is completed? There is a HPLUSARTFeedback interface but I could't find any implementation for it.
