nrf52840 Bluetooth and 802.15.4 multiprotocol example project

Question

Hi, 
 For a number of upcoming projects we require 802.15.4 and BLE dynamic multiprotocol support. We need to select a SoC to implement this. 
 We like the look of the nrf52840 and see multiprotocol should be possible using the nRF-IEEE-802.15.4-radio-driver. 
 A number of people have already asked about this but is there an example showing this working yet? Or if someone has got it working would firstly say they've done it and then, maybe, let us have the code ( or even binary ) please? 
 We have just had Silicon Labs pull 802.15.4 support from their modules that we were just about to design in so time is critical for us. We don't have the time to learn an API and get to grips with new hardware/software and the inevitable debugging to get to the point deciding to use the nrf52840. If we can prove multiprotocol works we will almost certainly use the nrf52840. 
 kind regards

Hi Edwin, 
 I'm having a problem getting this to work. 
 Firstly I got the single phy IEEE15.4 Radio Driver examples working. 
 I then modified the ble_zigbee_dynamic_light_switch_nus by stripping out any zigbee code. 
 I added the Radio Driver source files in. I've setup as described in the Radio Driver Wiki (i.e. RAAL_SOFTDEVICE defined, nrf_raal_softdevice.c added etc ). I used nrf_802154_clock_sdk.c, nrf_802154_lp_timer_nodrv.c. The nrf_802154_config,h files I left as is. 
 I call nrf_802154_init after setting up Bluetooth. 
 err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
 APP_ERROR_CHECK(err_code);

	/* Initialize loging system and GPIOs. */
 log_init();
 timer_init();
 leds_buttons_init();
 
 /* Bluetooth initialization. */
 ble_stack_init();
 gap_params_init();
 gatt_init();
 services_init();
 advertising_init();
 conn_params_init();
	
 printf("Initialise 802.15.4 ...");
 nrf_802154_init();

 nrf_802154_channel_set(11);
 nrf_802154_receive();
 printf("Done
");
	
	while (1)
	{
 if (!m_tx_in_progress)
 {
 printf("Send ");
 m_tx_in_progress = nrf_802154_transmit(message, sizeof(message), true);
 if (!m_tx_in_progress) 
 printf("Fail
");
 }	
	} 
 My understanding is the nrf_802154_init sets up the arbiter. 
 Running shows the bluetooth is working but it only sends a few 802.15.4 packets and then stops. nrf_raal_softdevice_soc_evt_handler is no longer being called. 
 Can you help please? I can post the project if required. 
 kind regards 
 Liam

You are right. Whilst it was called it was only a couple of times. 
 Registering the SOC_OBSERVER in main() fixed it and I am sending IEEE packets. Checking with a scope shows gaps in the stream where the bluetooth is active. 
 Might I suggest that the registration is mentioned in the Wiki. 
 Thank for your help Edvin and mrono.
