Can nRF51/52 detect a BLE collision signal or interference existed on the air?

[stephen]

We're considering nRF51/52 to implement a specific BLE application. We need the nRF51/52 go to sleep if a BLE collision signal or interference on an advertising channel has been detected. So, is it possible to detect this situation for nRF51/52?
It's well known that a BLE device can get the RSSI from the preamble of BLE packet and know another BLE is transmitting, but how about an interference, or BLE collision signals?
Can we know the AGC value to estimate the RX power of a collision signal or interference?

Welcome any solution and suggestion.

Thanks, Stephen

Hi,

Our nRF51/52 series implement something called a SoftDevice, this is a full implementation of the BLE stack that will run alongside your application. The SoftDevice will handle collisions, frequency hopping, retransmission etc.

The SoftDevice specification has more documentation and explanation on the functions of the SoftDevice.

Best regards,

Øyvind

I'm not sure to understand the answer - as I have the exact same question.

Does this mean that to get the answer, we have to skim the whole SoftDevice documentation, using grep or the like to find something like this? Weird.
