feedback on BT antenna activity

[ste2108]

Hello,

For our emission tests in an anechoic chamber we need to be sure that the BT antenna is up and running. Of course we cannot connect via BT from outside the chamber, even though we are pretty close to our device, and our solution up to now has been to use a development board inside the chamber connected to a PC outside the chamber through a USB cable and to the device itself through BLE, and using some BLE service to ping the board. I was wondering though if there is a reliable output from the Nordic stack which would allow us to get rid of the development board, and connect instead the device itself to the PC through a USB cable in order to collect this output on the PC. A function like "IsBLEAntennaUpAndRunning" would work, to be clear
Thank you.

Kind regards,

Stefano

Hi Stefano,

Is you device a custom board using the nRF5840 SoC?

And right now you are connecting this custom device via BLE to the DK (which DK is it?) both which are placed within the chamber and then the DK is connected via USB to the PC on the outside. Am I correct?

Regards,

Priyanka

Hello Priyanka,

SDK version is 2.8.0

The point is that I would like to avoid connecting the device under test via BLE to a second device which is within the chamber and cabled to a PC outside the chamber, and instead cable the device under test to the PC outside the chamber and use the output of some function to check that the BLE is up and running instead. What I am asking if there is such function, which should guarantee that the BLE stack is working correctly and that I would be able to connect if a device was present in the room.

yes, it is a custom board using nrf52840 SOC
