SimpleBLEPeripheral and 0x03E (FAILED TO ESTABLISH)

CC2652R: Connection Failed To Be Established(0x3E)

Part Number: CC2652R

On of the CC2652R used to work with a sensor, it can  scan, connect and read/write. Suddenly it stopped connecting but still it can scan. Not sure, why.

We changed the FW 5.10 and 5.20 but no success. Not at all connecting but RSSI level of the sensor is -65dBm. Same sensor can connect to another CC2652R still. So, sensor is perfectly fine and within the the range. Not sure, why suddenly stopped connecting. 

--->GapInit_connect

<---GapInit_connect status=0x00
<--event 0605; status 0 ; connectHandle 0000 connectRole 08
<--event 0606; status = 0 reason 0x3e (Connection Failed To Be Established)

    Hey Sen,

    Can you explain the high level of this application? Is the CC2652R configured as a peripheral or a central? I am confused as you have a sensor module (which I assume is a BLE peripheral) that fails to connect with a CC2652R. There can be many reasons why this is the case unfortunately.

    Do you happen to have a sniffer log of this?

    Hi Ammar,

    CC2652R is configured as central. Yes, the sensor is peripheral.  I ll update the sniffer log.
