Hi,

Yes you can measure RSSI in AP mode. But you can get relevant value only when one client is connected. In case of connected more clients as RSSI is returned average value from clients (that means values will not re relevant). To get RSSI you can use this code:

SlWlanGetRxStatResponse_t rssiRxStat;
int rssi;
if (sl_WlanRxStatGet(&rssiRxStat, 0) == 0) {
  if (rssiRxStat.AvarageDataCtrlRssi != 0) {
    rssi = rssiRxStat.AvarageDataCtrlRssi;
  }
} else {
  // wrong RSSI value
  rssi = -99;
}
