Hi Petter

It's working!

So I had better enabled the peripheral(which didn't be used in softdevice) with interrupt priority 1 or 3 before using it.

Thank you.

Now I was able to reproduce. sd_softdevice_enable() returns 0x1001 -> NRF_ERROR_SDM_INCORRECT_INTERRUPT_CONFIGURATION

This is because you have enabled the TIMER2 peripheral with interrupt priority 0, which is reserved by the SoftDevice. Add the following to remove the error:

NVIC_SetPriority(TIMER2_IRQn, 3);

Hi Petter

I am sorry that I forget to adjust main which run in trouble.

Can you adjust main as follow and try again?

int main(void)
{
    
    static uint8_t data_array[BLE_NUS_MAX_DATA_LEN];
    static uint8_t index = 0;
    uint8_t index_backup = 0;
    uint8_t newbyte;
		uint32_t isrunning = 0;
	
		g_CounterDriveSegment = 0;
	
		#ifdef NRF_RTT_SHOW
		SEGGER_RTT_WriteString(0, "Main Start!\n");
		#endif
	
    // Initialize
	gpio_init();
    timers_init();
	uart_init();
   // put start_timer2 will run introuble
	start_timer2();
   // put start_timer2 will run introuble
    ble_stack_init();
    gap_params_init();
    services_init();
    advertising_init();
    conn_params_init();
    sec_params_init();

    uart_putstring((const uint8_t *)START_STRING);
		
    advertising_start();

skip...
}

Seems to be working fine here. It advertises and I get the following in the RTT viewer:

 0> Main Start!
 0> Loop Start!

Do you have another chip to test with?

Could you test with the attached hex files:

Hi Petter

drive.google.com/.../view

I delete other project which was not used in SDK.

My project path is .\nRF51 SDK_v6.1.0.0\Nordic\nrf51822\Board\nrf6310\s110\nrf51-UART-examples-master\app_uart_library_example_with_ble

If I loss something, please tell me.

Thanks.

Strange. Could you upload your complete project so I can test it here?

Hi Petter

I put some printf in "SOFTDEVICE_HANDLER_INIT".

But it didn't finish "softdevice_handler_init".

So I didn't get ERROR_CODE value.

Where does it reset? Do you get to ble_stack_init()? Have you seen this?

Hi Petter.

I debug with RTT viewer by "SEGGER_RTT_WriteString" and "SEGGER_RTT_printf".

When "start_timer2();" is before "ble_stack_init();", process reset repeatedly and return to beginning of main.

"ble_stack_init();" seem contain something about "softdevice_handler_init", lfclk init, ...

I don't know how it work and take how it affect timer2(Maybe it affect hfclk actually).

RE: Timer interrupt don't work in ble_app_uart of SDK6.1.0

Petter Myhre — Fri, 07 Apr 2017 11:43:22 GMT

Ok. So what happens when put it after timers_init()? Are you able to execute the start_timer2() function? Do you get to ble_stack_init();? Please try to use the debug.

Same time? How are you measuring this?

RE: Timer interrupt don't work in ble_app_uart of SDK6.1.0

pikachu — Fri, 07 Apr 2017 03:20:14 GMT

Hi Petter.

I fix code by calling "sd_clock_hfclk_request();" instead of "NRF_CLOCK->TASKS_HFCLKSTART = 1;" But it still work in trouble.

It can work when "start_timer2();" is after "uart_putstring((const uint8_t *)START_STRING);", but not work when "start_timer2();" is after "timers_init();".
Timer2 interrput is triggered with the same time, no matter NRF_TIMER2->CC[0] = 1 ,10, 100. Maybe the higher priority interrupt be triggered, and take long time.(I guess it's BLE or uart)

RE: Timer interrupt don't work in ble_app_uart of SDK6.1.0

Petter Myhre — Thu, 06 Apr 2017 13:59:08 GMT

Ok. I would recommend you to look into how to use the debugger.

Maybe the problem is that you are accessing the NRF_CLOCK peripheral directly? This is a restricted peripheral when the SoftDevice is enabled, see Section 11.3 in the S110 SoftDevice specification 2.0 for more information. You can instead try to call sd_clock_hfclk_request().

Hi Petter. I am sure I have configured the GPIO to be an output. And function "TurnonLEDx" actually working. I don't know how to step by step debug with nrf51288 directly. I program with Keil5. I first build a hex file,then upload "S110 SoftDevice v7.0" and "hex file" by "nrfgo studio". I also put TurnonLEDx and delay in TIMER2_IRQHandler(),but it doesn't be trrigged.

Petter Myhre — Thu, 06 Apr 2017 11:49:11 GMT

Have you configured the GPIO to be an output? nrf_gpio_cfg_output()? Are you sure that nrf_gpio_pin_set() will turn the LED on? Maybe you have to call nrf_gpio_pin_clear()? Have you tried to use the debugger? If you put a breakpoint in TIMER2_IRQHandler(), do you hit it?
