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?

Glad you were able to figure it out Ali!

As for your request Andrew, most modules mention in their data sheets what clocks are included and not. But I'll suggest internally to make this more clear from our side.

Best regards,

Simon

But that's not what catches people out; eg, only today:

https://devzone.nordicsemi.com/f/nordic-q-a/48136/using-soft-device-on-custom-board-with-nrf52840/190699#190699

They say what clocks are included & not - but they don't (apparently) explain the implications of that.

Yet another 'Gotcha!' with the internal RC:
