Reading RSSI values Radio Test example

[sachin.singh]

Hi,

I am developing one of the code for the radio testing & in which I need to pass or select the receiving channel and at same time need to receive the RSSI value of same radio.

I am developing it on the custom board with nrf51822 chip. Need to develop the same for radio testing requirement.

Can anybody please suggest or guide me for the same for developing the code.

Thanks

Hi,

Which SDK version are you using? Are you using an example from the SDK? Can you post some code that show what you are doing?

This is the relevant section on RSSI from the nRF51 reference manual:

Sampling of the received signal strength is started by using the RSSISTART task. The sample can be read from the RSSISAMPLE register. The sample period of the RSSI is defined by RSSIPERIOD, see the device product specification for details. The RSSI sample will hold the average received signal strength during this sample period. For the RSSI sample to be valid the radio has to be enabled in receive mode (RXEN task) and the reception has to be started (READY event followed by START task).

Best regards,
Jørgen
