Hi. How can i read the RSSI of BLE connection inside the program (not with external tool)?

[Remi QUINTIN · Accepted solution]

The RSSI is part of the advertising packet received from the BLE stack. See the picture detailing the advertising packet structure.

The RSSI is the Tx Power level. You can check the AD type and the RSSI value is the data next to it.

You can also read this information using the command HCI_READ_RSSI (see AN5270).
