nRF52833 has an error in LongRange mode:NRF_LOG_ERROR("SOFTDEVICE: ASSERTION FAILED")

[Hannibalhz]

Dear Nordic engineers

        I recently encountered a problem while developing the program of nRF52833.My program is developed on the basis of nRF5SDK 16.0, using S140 softdevice.I modified the PHY of the two programs ble_uart and ble_uart_c to LongRange mode, which is used by the two hardware. The peripheral collects data regularly and sends it to the central.

       This is no problem when the peripheral and central signals are relatively good.But when the signal is poor or when the peripheral and the central are tested for a long distance, there will be problems, and the peripheral will restart in the place where the signal is not good.

     I turned on DEBUG and saw that the chip entered app_error, and the RTT print at this time was "SOFTDEVICE: ASSERTION FAILED"，It is the error code shown below, please tell me how to do it.

      Looking forward to your reply and thank you for your support

Hi

There are a few other changes that are necessary when enabling the Coded PHY in an example using the Uncoded PHY(s). My colleague Vidar modified the ble_app_uart and ble_app_uart_c examples to use Coded PHY by default in this case, so you can use that for reference.

Keep in mind that the advertising data flags (init.advdata.flags) must be set to BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE, which I think was missed in Vidar's example if my memory serves me correctly.

Best regards,

Simon
