BLE 6LoWPAN environment about coap example

[abc]

Hello, I build a BLE 6LoWPAN environment on my raspberry pi with Kernel 3.18.3 and connect a BLE Dongle. The BLE Node is Arch BLE (www.seeedstudio.com/.../Arch-BLE-p-1998.html). and follow Nordic nRF51 IoT SDK. I successfully testd ipv6_icmp example. But when I try ipv6_coap_serverexample, node not start advertising. i follow Iot_SDK_step_by_step.pdf use s1xx-iot-prototype2_softdevice.hex nrf51422_xxac_s1xx_iot.hex into my node. discover the advertising device by using the hcitool lescan command. but not receive advertisement from node. anyone know what’s wrong about this problem? thank!

@abc: I think this issue has nothing to do with the Raspberry PI. There must be smth went wrong with the Arch BLE.

Have you tried to scan for advertising packet with Master Control panel (on PC or Android) or other scanning tool ?

Could you run the device in debug mode and add a break point in app_error_handler() ?

I suspect that there could be smth wrong with the UART lines that if you setup the app_trace_init() with HWFC set to true and if you send smth via UART you will get stuck if you don't have the UART line configured correctly and have a UART peer device to read the UART data.
