Scanning its own advertising in ble multirole example

[Vivek_Core]

Hello,

I am working on project where my requirement is something like... Device will advertise and it gets scanned by its own scanning.

What I have done so far...

1. nRF52840_DK is running a example "ble_app_multirole_lesc".

2. nRF52840_DK is advertising with the name "ABCD1234" (DEVICE_NAME = "ABCD1234") and it also initialized the scanning by setting the filter SCAN_NAME_FILTER (m_target_periph_name = "ABCD1234") with the same name.

3. I printed out the Mac address those are get scanned in scan_evt_handler -> NRF_BLE_SCAN_EVT_NOT_FOUND.

4. Now I want that nRF52840_DK advertisement ("ABCD1234") gets scanned by it own scanning.

But the problem is... nRF52840_DK advertisement didn't get scanned by its own scanning and also no mac address printed, It gets scanned in mobile application "nRF Connect". So I can say there is no problem in advertising as well as in scanning also.

Is there any other way by which I can start advertising in nRF52840_DK and also it gets scanned by its own scanning ?

Thanks

Vivek

Hi Vivek, 

That will not be possible, the radio can't be both in receive and transmit mode at the same time. When you switch mode to TX to transmit the advertising packet, RX mode will be disabled. Once the packet is transmitted on-air you can switch back to RX mode, but then the on-air transmit will be done and the packet is lost.
