GAP server event to get client rssi

[igna09]

Hello,

i ported my project from bluedrod to NimBLE
thank you for your amazing work

In my project i need to get rssi of connected client

in bluedroid I used to make this:

esp_err_t rc = esp_ble_gap_read_rssi(this->authenticatedBdAddress->getNative());
...
customGapCallback(esp_gap_ble_cb_event_t event, esp_ble_gap_cb_param_t *param) {
    switch(event) {
        ......
        case ESP_GAP_BLE_READ_RSSI_COMPLETE_EVT: {
            String message = "[status: ";
            message += param->read_rssi_cmpl.status;
            message += ", rssi: ";
            message += param->read_rssi_cmpl.rssi;
            message += ", remote_addr: ";
            message += BLEAddress(param->read_rssi_cmpl.remote_addr).toString().c_str();
            message += "]";
...
            break;
        } // ESP_GAP_BLE_READ_RSSI_COMPLETE_EVT
    }
}

In NimBLE I can't find a way to trigger event ESP_GAP_BLE_READ_RSSI_COMPLETE_EVT to get rssi

You don't need to handle an event here for this. There is a low level function you can call: int ble_gap_conn_rssi(uint16_t conn_handle, int8_t *out_rssi);

I will look to add this to the CPP API in the future.
