Bluetooth: IPSP Sample Crash on nrf52840dk_nrf52840 #53871

Closed seekaddo closed 11 months ago

seekaddo commented 1 year ago

Hi All, I am new to the zephyr OS and currently using it for an IoT project. I am trying to get the IPSP example working so that i can start from there. The example keeps crashing on connect (echo "connect DC:F2:F1:E7:96:E9 2" > /sys/kernel/debug/bluetooth/6lowpan_control) and I don't know why. Can anyone help? I am working with the latest branch.

commit 80f87b94806bef4f893b18f1dc8cea070382dd6b (HEAD -> main, origin/main, origin/HEAD) Author: Mariusz Skamra mariusz.skamra@codecoup.pl Date: Thu Jan 12 10:51:19 2023 +0100

To Reproduce

west build -p always -b nrf52840dk_nrf52840 samples/bluetooth/ipsp -DCONF_FILE=prj_dbg.conf
west flash

on Raspi Pi 3B Using this USB BLE dongle: https://www.2direct.de/media/pdf/fb/99/d0/bt0015IJ77DTdbLHOls.pdf

modprobe bluetooth_6lowpan
 echo 1 > /sys/kernel/debug/bluetooth/6lowpan_enable
 echo "connect  <nRF MAC> <type>" > /sys/kernel/debug/bluetooth/6lowpan_control

@seekaddo could you try on the latest origin/main? https://github.com/zephyrproject-rtos/zephyr/pull/67531 might have fixed IPSP, but I'm not sure.
