nrf52833 - How to reset the esb communication ?

[Joel V]

Hi Dev Zone !

I would like to do a complete reset to the ESB communication in my application when there is a problem with it for any reason whatsoever. This is what I have done and it does not seem to solve the communication problems that can occur:

uint32_t mesh_reinit()
{
    uint32_t err_code;
    mesh_stop_rx();
    mesh_flush_rx();
    nrf_esb_flush_tx();
    err_code = nrf_esb_init(&nrf_esb_config);
    if(mesh_config.is_listening)
    {
        err_code = nrf_esb_start_rx();
        VERIFY_SUCCESS(err_code);
    }

    VERIFY_SUCCESS(err_code);
    return NRF_SUCCESS;
}

SDKs :

• nRF5_SDK_16.0.0
• nRF5_SDK_for_Thread_and_Zigbee_2.0.0_29775ac_min

Do you have any suggestion ?

Thanks !

Before reinit can you try to do a full power cycle or the radio core by:

*(volatile uint32_t *)0x40001FFC = 0;
*(volatile uint32_t *)0x40001FFC;
*(volatile uint32_t *)0x40001FFC = 1;
