Zigbee debugging

[mathiasvanbelle]

Hi,

I'm using the NRF52840 with the "nRF5_SDK_for_Thread_and_Zigbee_2.0.0".

I tested the zigbee light_bulb example and zigbee light_bulb + ble. It works fine so my next step was to do combination with my own ble service in a existing project.
In my new project the ble part works fine. The zigbee (still the light bulb example) part does not work at the moment. When i sniff, i don't see the Beacon request frames.

When i look at the uart logging i still see "Production config is not present or invalid" and "Failed to join network. Status: -1".

extra info:
i used sd_softdevice_vector_table_base_set((uint32_t) vector_table) to change the vector table to RAM. For the Zigbee part i registered the following interrupts: 

SysInt_RegisterIsr(TIMER3_IRQn, (ISR_CALLBACK) TIMER3_IRQHandler);
SysInt_RegisterIsr(SWI3_EGU3_IRQn, (ISR_CALLBACK) SWI3_IRQHandler);
SysInt_RegisterIsr(RTC2_IRQn, (ISR_CALLBACK) RTC2_IRQHandler);

this is needed if i look at the documentation. 

My goal is to let the zigbee and the BLE part to work together in my code. Any tips how to debug the Zigbee part so i can figure out the problem?

Best regards,

Mathias

Packet sniffing while connecting to Alexa over zigbee - no connection happened

sniffer_eddystone_zigbee_alexa_success.pcapng

This is a packet sniffing with the eddystone example - connection successfull.

The MAC of our nRF52840 DK is 40 02 2B A8 6A 0E 01 0B

The MAC of Alexa is 5C:41:5A:E4:F0:D7

Could it be possible that the commissioning is failing ? This could explain why I don't see the APS packets in my project, while I do see some APS packets in the "eddystone" example.

But how can I figure out what is going wrong now ?

[Dimitri G]

Further investigation from my part reveils that in my project, the call to zboss_signal_handler(zb_uint8_t param) for signal ZB_BDB_SIGNAL_DEVICE_REBOOT, the param argument is 0x0B.  The status becomes RET_ERROR.

While in the example project, the param argument is 0x0A and the status becomes RET_OK.

Maybe this information helps to give some support from the Nordic engineers ?

Thanks

Hello,

I have forwarded your logs for decryption. Maybe they can give some more hints on what's going on.

You have the same network settings in your application as it was in the unmodified eddystone example? Same zigbee channel?

It may be if you are running the examples on the same board that your device thinks it is already commisioned, if the flash is not erased properly. Can you make sure that you erase all the flash before you try to run your custom example? You can use "nrfjprog -e" if you have the Nordic's command line tools installed. Then try to flash your application.

If the board thinks it is commissioned, and tries to join the network as another device, Alexa may reject it. 

Can you try to erase the chip, run your application, and let me know if that makes any difference?

Best regards,

Edvin
