[Tinyos-help] Problem with mspgcc code generation for nested if-else blocks?

Hi All, I had sent this mail to mspgcc mailing list but did not get any response. I use TinyOS 1.x on a Tmote Sky. I wrote a function which has a set of nested if-else blocks. Ultimately, the function returns a result. After many months of successful operation, the code stopped working as intended

[Tinyos-help] TinyOS 1.x and higher versions of mspgcc

Hi All, I use TinyOS 1.x ( I have some valid reasons to use it still ) on Tmote Sky. I ran into trouble due to a bug in mspgcc, possibly related to pointers to an array of structures. A similar bug is mentioned here: http://sourceforge.net/mailarchive/message.php?msg_id=43C428A6.9040209%40aa

[Tinyos-help] Packet loss on Tmote (using TinyOS 1.x)

Hi folks,  I find that on Tmotes (tinyos 1.x - latest CVS files for CC2420RadioM.nc and CC2420RadioC.nc)  there is significant packet loss (while sending) under the following conditions :  a) There is only one mote on the channel   b) Multiple packets are sent one after the other.  c) The packets a

[Tinyos-help] CC2420 Errata Note 003, rev 0.3 : Setting RXCTRL1.RXBPF_LOCUR

Hi All, One of the Chipcon errata notes suggests setting the RXCTRL1.RXBPF_LOCURbit. This is a fix for a problem that occurs when the VDD pins are supplied with voltage less than 1.8 V. Importantly, it also notes that setting this bit will also reduce Rx current consumption by 1.2 mA ! I do not

Re: [Tinyos-help] Configuring Tmote Connect

broadcasts as those packets are not IP packets. So the TMote Connect could still have assumed the IP address 192.168.1.77. You could try to reach the TMote Connect by just assuming that it has the IP address 192.168.1.77. If you try a ping, the device should at least answer the ARP request. Chee

[Tinyos-help] TinyOS 1.1.15 on Tmote Sky : UART0/Radio bug due to clock source setting

Hi All, This is regarding usage of UART0 and radio on Tmote Sky under TinyOS 1.1.15. I was using UART(at 9600 baud) on USART0 and the radio in sequence, periodically. I observed the following quirky behaviour : Once we transition from UART mode to radio mode, if we call a Send.send , Send.sen

[Tinyos-help] Questions on Routing protocols with downstream message support

Hi Omprakash,I was using a wrong method to calculate accuracy.After correcting my method, I find that the time sync accuracy with FTSP is indeed of the order of 2-4 clock ticks on Tmote.

Hi Cory,   This is with reference to the volcano monitoring paper of Matt Welsh and his team  (mentioned below).  In this paper, two problems have been mentioned with regards to FTSP.  1) The problem with the clock driver (apparently seen only on Tmotes) that seems   to return bogus timestamps.

Re: [Tinyos-help] FTSP on Tmotes

seems like there is still an infinitesimal chance getting of a corrupt reading, though a corrupt reading is at least significantly less likely than before.  Asserting anything stronger than that would require a longer study which I have not performed. CoryOn 9/25/06, harish prabhu < [EMAIL PROTECTE
