[Linux-zigbee-devel] Cannot get MRFs talking. Not sure what I've done wrong.
I am trying to get a MRF24j40 on a BeagleBone Black to talk to an arduino with
a mrf24j40. I have successfully communicated arduino to arduino but as of yet
have not been able to receive the packets being sent out on the BBB.
The setup: I have GPIO_13 going to reset (pin 2), GPIO_14 going to wake (pin
3) and GPIO_29 going to interrupt (4). The 3.3v is going to vin on 10 and
ground on pin 1. I am using SPI1 with the HDMI ports disabled. D0 is mapping
to pin 7 (SDO) and D1 is mapping to pin 5 (SDI), P9.31 the clock goes to pin 6
and P9.28 goes to pin 8.
I have been able to log into the BBB via ssh. I then load the cape for the
MRF24j40 using the echo to /sys/devices/bone_capemgr.9/slots
This appears to load the driver properly.
I have then been able to do:
iz listphy
iz: /lib/arm-linux-gnueabihf/libnl-genl-3.so.200: no version information
available (required by iz)
iz: /lib/arm-linux-gnueabihf/libnl-3.so.200: no version information

channels on page 0: 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

iz: /lib/arm-linux-gnueabihf/libnl-3.so.200: no version information
available (required by iz)
Registered new device ('wpan0') on phy wpan-phy0
I decided to set all my addresses to simple things on the arduino side in case
there is some sort of endian problem so the pan id is 0, the address of the
sender is 0 and it sends the data to 1, thus I try to set the beaglebone to pan
id 0, address 1 with a destination address of 0.
root@beaglebone:~# iz set wpan0 0 1 12
iz: /lib/arm-linux-gnueabihf/libnl-genl-3.so.200: no version information
available (required by iz)
iz: /lib/arm-linux-gnueabihf/libnl-3.so.200: no version information
available (required by iz)
ifconfig wpan0 up
Then I run
izchat 0 1 0
I get nothing on the BBB side even though the other side is constantly
transmitting... and when I type into izchat, I do not receive anything on the
other side.
Any help here would be appreciated... I just want to see some data before I
start coding. Like I said, this has been tested arduino to arduino and does
not have problems.

Mailinglist changed to [0].
Please let me know which kernel, libnl3 and lowpan-tools version do you
use.
Also I need to notice you that I am working on a big rework. With new
userspace tools, etc... I need some time to bring it mainline. The bring
it mainline thing is currently in progress.
I am very busy right now.

I am using kernel: Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux can you try to use bleeding edge kernel?

These are the versions that I downloaded and compiled. drwxr-xr-x 11 debian admin 4096 Oct 28 2014 libnl-3.2.25 drwxr-xr-x 11 debian admin 4096 Oct 28 2014 lowpan-tools-0.3.1 this looks fine. and just to confirm that they updated: root@beaglebone:~# iz --version iz: /lib/arm-linux-gnueabihf/libnl-genl-3.so.200: no version information available (required by iz) iz: /lib/arm-linux-gnueabihf/libnl-3.so.200: no version information available (required by iz) mhhh, I didn't get such warning. iz 0.3.1 Appreciate your help Alex. Right now I’m under water as well so I understand your pain. Let me know if I can help in anyway Just try a bleeding edge kernel and try again. Then we can see what's going on there. Also set a eui-64 address (extended address) before running iz set. You can do that by ip link set $WPAN_INTERFACE address $EXTENDED_ADDR. exmaples for variables: WPAN_INTERFACE=wpan0 EXTENDED_ADDR=aa:aa:aa:aa:aa:aa:aa:aa Please do these steps while $WPAN_INTERFACE is down. - Alex [0] http://git.kernel.org/cgit/linux/kernel/git/bluetooth/bluetooth-next.git -- ___ Linux-zigbee-devel mailing list Linux-zigbee-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-zigbee-devel
