Error 133 (0x85): GATT ERROR

Lalabhai Desai

Hello,

We are using nrf52805 for our project. Facing some errors like "GATT ERROR" and GATT INSUF AUTHORIZATION and GATT CONN TIMEOUT ERROR" when I want to upgrade my application using "nrf connect'mobile application.

I am successfully able to upgrade my application first time, means I can able to upgrade my application from "DFUtrg" and also able to see my module name on "nrf connect" utility but If I am trying to upgrade again then connection was not established and getting above mentioned errors.

Please give me some solution for this problem.

Regards,

Lalabhai

    Hi

    Can you provide some more details about your application. Do you have both a UART + BLE bootloader. Have you made this yourself by combining two of our projects or similar? i would suggest trying out the _debug bootloader project(s) we have, so you can get some information from the bootloader log as well.

    Can you also find out what functions return these INSUF AUTHROIZATION and GATT errors?

    What function

    Best regards,

    Simon
