Read RSSI value

Hello,

I'm using 2 nRF58840 dev kit with SDK 14.2.0. I'm trying to read the RSSI value of the second board from the first board using LE Coded PHY in both modules.

I started with the "ATT_MTU Throughput" example which worked correctly when choosing the LE coded PHY.

I changed the "DEVICE_NAME" so that no connection will be established. In the BLE_GAP_EVT_ADV_REPORT event, I put this below line to display the RSSI value

if ( p_gap_evt->params.adv_report.scan_rsp )
       NRF_LOG_INFO("rssi =%d dBm",p_gap_evt->params.rssi_changed.rssi);

When running this code no BLE_GAP_EVT_ADV_REPORT event corresponds to the scan_rsp. also no BLE_GATTS_EVT_TIMEOUT events aswell.

My questions are :

  • any thoughts of what might be wrong in my configuration ?

  • When executing sd_ble_gap_scan_start(), the BLE_GAP_EVT_ADV_REPORT will be set each time a device is discovered or it after 'scan window' time ?

-When using only the LE coded PHY, the nRF module will only see modules advertising on the same physical layer ?

  • sd_ble_gap_rssi_start() function require a connection, is there another function that scans for the RSSI of visible devices ?

Any helps would be very appreciated

Thank You Chaabane
