hello,

I want to know if it is possible to get the RSSI value of a node with this function in BLUENRG-1 without the mesh network.

tBleStatus hci_read_rssi (uint16_t Connection_Handle, uint8_t *RSSI);

Can I use this if yes how? Because I am getting only the value 128 or 18 from this function.

Thank you

Hello Fahad, to use the api mentioned hci_read_rssi (uint16_t Connection_Handle, uint8_t *RSSI), connection handle should be known apriori. It is straight forward without mesh network. Just make sure that board maintain gatt connection with Android in order to do so.

Smartphone shows RSSI value of packets received from board. RSSI value of packets from Android is read either by using hci_read_rssi if connection is made or hci_le_advertising_report_event if smartphone is discoverable.
