RTOS/CC2640R2F: Read Rssi from Peripheral，the Rssi value has a high probability of HCI_RSSI_NOT_AVAILABLE(0x7F)

Hi,

Do you mean the RSSI reading on the smartphone side?

No, the RSSI reading on the peripheral(2640R2F LAUNCHPAD).

How do you read RSSI?

Are you able to sniff the communication and thus get another set of RSSI measurement for comparison?

Please refer to the attachment, we made modifications base on project zero.

And click the Button0 on the  LAUNCHPAD, would start timer to read rssi:

        uint16_t connHandle = 0xFFFF;  // connection handle
        GAPRole_GetParameter(GAPROLE_CONNHANDLE, &connHandle);
        if(connHandle != 0xFFFF)
        {
            // Read RSSI
            VOID HCI_ReadRssiCmd(connHandle);
        }

Now, we have only one LAUNCHPAD, our application scenarios is that cc2640r2 as a peripheral gets the rssi value which is from connected mobile phone, and do something.

Thank you.

Hi,

What SDK version and BLE-Stack (5.0 or 4.2) version are you using?

SDK version:simplelink_cc2640r2_sdk_3_10_00_15

BLE-Stack: 4.2

Thank you.
