BLE twi freertos conflict nRF52840

[JAC]

I am unable to get logging working. (This is the subject of another issue I have raised, logging does not work in the hrs freertos sdk 16 example.)

I'm trying to read pressure data from the BMP280 pressure sensor over I2C on the nRF52840 using freertos.

I can read and write to the sensor without the BLE.

I can send simulated data by BLE without the TWI.

The two together cause a conflict and crash the program.

Setting breakpoints causes unpredictable behaviour and I'm unable to get logging working as stated above.

Any ideas where I should now look?

Hi,

Have you tried debugging the application, to check if there are any error codes reported? You should be able to set breakpoints, but you cannot step the code after softdevice is enabled, as this will cause softdevice asserts. I would recommend to set breakpoint in the error handler, to check if any error codes are reported.

Are you using any of the blocked/restricted peripheral used by the softdevice in the TWI part of the application?

Best regards,
Jørgen
