Thanks, but for me the TICKET is closed because we found the problem.

When the connection bluetooth go down the micro sometimes go first in dle_state_handle(); before calling deinit TWI.

making the state machine work well with the appropriate traffic lights everything works well.

We have now dicovered that the micro goes in HardFault handler (NRF_ERROR_INVALID_STATE on nrf_drv_gpiote_in_init) after init TWI because the TWI is already initialized.

The problem is that when the bluetooth connection go down before go in idle_state_handle(); we deinit the TWI but the TWI does't not diinit.

WHY ?
