nRF Connect GATT Timeout After Connecting To Device

Hi,

My device advertises and "connects", but then I later receive an error through nRF Connect: "Error: Received a GATT Timeout".

Has anyone else had a similar problem, or if not, any ideas on how to fix this?

Thanks!

  • Hi Amanda,

    1. I am using SDK 16.0.0, implementing a version of the BLE multiperipheral example

    2. I never actually receive a reason in the NRF Connect Log. What happens eventually is a pop up shows up with the “Error: received a GATT timeout” message. The device remains “connected” but NRF never updates its name from “Unknown” or shows its services

    3. I am using a nRF52840 Dongle as the adapter and a standard issue nRF52840-DK as the peripheral

    4. Unsure, could you please tell me how I could get a peripheral-side error log?

    5. I’ll look into it and get back to you as soon as possible, thanks!

    What did you modify the BLE multiperipheral example? Could it work without the modification?

    Please provide the nRF Connect log by

    If you want to use an RTT viewer, you could enable NRF_LOG_BACKEND_RTT_ENABLED in the sdk_config.h. Then, you could get the RTT log in the Segger. 

    //==========================================================
    // <e> NRF_LOG_BACKEND_RTT_ENABLED - nrf_log_backend_rtt - Log RTT backend
    //==========================================================
    #ifndef NRF_LOG_BACKEND_RTT_ENABLED
    #define NRF_LOG_BACKEND_RTT_ENABLED 1
    #endif
     

    Otherwise, Start a terminal emulator like PuTTY and connect to the used COM port with the following UART settings:

    • Baud rate: 115.200
    • 8 data bits
    • 1 stop bit
    • No parity
    • HW flow control: None
