I've added the two other files as well.

Thanks you morten, please send me the other two files also. And please look at this link and give your suggestion https://devzone.nordicsemi.com/index.php/how-to-test-the-radio-on-the-hardware#reply-236.

I've attached the main file, but the modifications from your example is minor, except for removing some of your code and removing the reset.

Thank you Morten. If possible please upload the source code with changes you made on it. It will be somewhat helpful for us to find the exact source of the problem.

Once I fixed your compilation errors by commenting out code, so that a binary was actually generated, I was not able to recreate any problems. I added a case to main.c's on_ble_evt(), and everything worked as expected. I'd strongly recommend you to do a real clean up of your code, as it seemed extremely messy right now, which might very well be the cause of your problems.

While developing, you should also make sure to not do a reset in app_error_handler, but instead have an infinite loop so that you can catch errors.

Thanks for your reply, I uploaded the modified source code, please refer it and give us your suggestion.

Handles are assigned sequentially from 1, so there is no way that you can have a handle that is 0xB001 (= 45057), since there is simply not enough RAM on the nRF51822 to have that many handles. This issue must therefore stem from something else.

Can you please upload your complete application, so that I can have a look at it?

Edit: I've now had a look at your code, and adding this to main.c's on_ble_evt, made it reset on device name writes as expected:


static void on_ble_evt(ble_evt_t * p_ble_evt)
{
...
    ble_gatts_evt_write_t * write_evt;
...
        case BLE_GATTS_EVT_WRITE:
            write_evt = &p_ble_evt->evt.gatts_evt.params.write;
            if (write_evt->handle == 0x03)
            {
                sd_nvic_SystemReset();
            }
            break;
...

I'd strongly recommend you to clean up your code until you get it working and only then add things back in to see what causes your problem.

Edit 2: I've attached the main file after my modifications, but I haven't done any effort on fixing the other mess.

main.c

ble_hrs.c

ble_hrs.h
