BLE antenna test with Radio test

[elektron314]

Hi!

I have nRF5340 Devkits and already have my own PCBs with nRF5340 chips onboard. I have a task where I need to evaluate how good will be BLE signal in different locations inside of our device (box with metallic walls and covers).

I was thinking that I could measure RSSI of devkit in different position with Radio test example firmware but with iOS nRF Connect app I can see around 50 bluetooth devices around me but not my Devkit. At least I don't see it's name. It seems like they don't populate it in their advertising. Talking either about if Radio test example work or not I can say that two devkits with it onboard can connect to each other and transceive and receive right data pattern without losses.

Question:

How can I evaluate bluetooth quality connectivity inside of our device with standard Radio test example?

What are the other options to do that?

Added:

Here (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/peripheral/radio_test/README.html#testing-with-rssi-viewer) they say in the topic Testing with RSSI Viewer

7. Start the RSSI Viewer application and select the kit to communicate with.

I can't select the kit, it doesn't have name or something wrong.

Hi,

The radio test example does not use Bluetooth, and is intended to be used in lab tests, typically with a spectrum analyzer. For the practical test you describe I suspect that the best would be to pick a peripheral Bluetooth example. Either use a beacon and observe the RSSI on the phone when it is just scanning, or use a sample that maintains a connection (like Bluetooth: Peripheral LBS) and check when you get a disconnect.

Thanks! It works.
