NCS Conflict between Timer Interrupt and BLE stack?

[Mr.NCK]

Hi,

  I want to use timer interrupt in BLE code. If enable timer inside the BLE code. The code will not work properly. I want to know why this is happening like that and how can I implement the timer interrupt inside the BLE code. I am using nrf5340dk and NCS v 1.9.1 SDK. And also I want to check with the same code GPIO Interrupt and delay also not working fine. Kindly, help me to resolve the issue

Thanks & Regards,

Hi Navin,

How have you implemented your timer?

The code will not work properly.

How do you observe this?

Is your code based on any sample? Please check out the zephyr/samples/basic/button for an example showing how to use GPIOs.

Hi Helsing,

In the BLE application. I have tried to implement the below function.

 k_timer_start(&led_timer, K_MSEC(5000), K_MSEC(5000));

I haven't gotten any compile error. But in the run time I can't be able to see any output an as well my BLE advertisement also gets stopped.

Thanks & Regards

Hi Helsing,

This is the actual problem we are facing

We using NRF Connect SDK(zepher)

1. After BLE is enabled, gpio interrupt handler is not at all gettting executed

2. Regards the timer0 which we tried, we are getting os fault if we enable IRQ handler.

3. is it possible to use timer0, timer1 and timer2 if ble is enabled and if yes please share the reference

Thanks & regards,

Navin

Hi Navin, sorry for the delay.

Would you be able to share your code?

Are you calling any 'k_timer' functions from any interrupt context, or from inside a callback? If so, then one solution is to use a work item instead. Submit the work item, then call the k_timer from the work item.

Here is the documentation for workque threads and items.

Best regards,

Håkon

Edit: Updated faulty link.
