Error 133 (0x85): GATT ERROR on nRF52840

[Ali Rumane]

Hi,

I am running ble_app_blinky example on nRF5280 custom board, it is giving me Error 133 (0x85): GATT ERROR. Since I have nrf52DK, I tried same example with SD 132 on nrf52832 it works as expected.

I went through devzone and there are many questions with similar issues but  couldn't find a solution.

Could you please let me know what could be reason for the same?

Indeed!

And not just on the Devzone - also elsewhere on the internet.

It seems to be just a generic "something went wrong, but we don't know what" code. Not very helpful.

I have been seeing it when adding new Services and Characteristics when the implementation was incomplete - so the peripheral was, effectively, just ignoring stuff from the Central.

Sorry that doesn't help much, but it probably indicates a Bug(s) in your Service and/or Characteristic handling

Hi,

Thank you for your reply.

I almost forgot to mention that I am adding new service in my application from this example.

I didn't modify much code but there are few changes I made.

Could you please recommend some example where I can look to implement a custom service which has read and write permission.

I went through LED Button Service and NORDIC UART Service, they don't have the read and write permission. I will look into few more examples.

Thank you for mentioning it. I will look into it.

I am trying to flash default blinky appliction on Laird’s BL654 module, it is showing Error 133 (0x85): GATT ERROR. I didn't modify existing code so I am expecting the code to run smoothly. I have nrf52DK on which I tried same example, it works as expected.

What possibly could go wrong?
