app_timer_t' has no member named 'handler' (I got this error after merge the I2c OLED project with ble_template example)

[luqman]

Hi.

I recently started work on some projects where I have to use I2c OLED and BLE. I used OLED to display time which is running on an internal RTC of nrf52832. 

Now I merge my Oled code with the ble_template example to advertise. But I got an error on app_timer2.c fie which is redirected some function to (drv_rtc.h). 

how I try to solve this problem but fail,..

Add the path of the file 

Enable timer

#ifndef APP_TIMER_ENABLED
#define APP_TIMER_ENABLED 1
#endif 

Error looks like:

Thanks for the answer I just added the path and enable App_time and now it's working but I have another issue now :( 

Combine ble_app_template example with clock code which is nearly run separately.  After combining

I am happy to hear that it resolved the issue, great!

That sounds like a non-NRF_SUCCESS error code being passed to an APP_ERROR_CHECK. Please make sure to have DEBUG defined in your preprocessor defines, like shown in the included image.
 
This will make the logger output a detailed error message whenever a non-NRF_SUCCESS error code is passed to an APP_ERROR_CHECK. Check the error code in this error message against the API Reference of the function that returned it, to see why it generated the error.

Best regards,
Karl

[luqman]

thanks for the answer Karl.

I added that the the debug window shows this 

<info> app_timer: RTC: initialized.
<info> app: Template example started.
<info> app: Fast advertising.
<error> app: Fatal error

when the code redirects to the advertising mode function this makes reset the microcontroller I don't understand.

I use RTC0 for clock count is there any possibility that the ble advertising conflict with the RTC or maybe some thing else

No problem at all, I am happy to help!

If the microcontroller resets that usually means that a non-NRF_SUCCESS error code has been passed to an APP_ERROR_CHECK, like mentioned in my previous reply.
Rebooting the device is the default error handling, when no specific error handling has been implemented.

luqman said:

Yes, RTC0 is blocked by the SoftDevice. You will have to use another RTC instance.
Try this, and let me know if it resolves your issue.

Karl

No, it's still the same as I change the RTC- ----> RTC2  

I use nrf_calender_example and here I change the clock 

#define CAL_RTC                 NRF_RTC2

[Karl Ylvisaker]

Please try to put some breakpoints in your code, to see where the fatal error occurs.
I see now that you are triggering the HFCLKSTART task after having enabled the SoftDevice, this may be causing the error.

Use the breakpoints to see how far you are getting in your code, to pinpoint exactly which line is causing this. Do you for example ever enter into the nrf_cal_init function?

For the record, your code includes a lot of commented out code, clutter, and improper formatting (such as the uneven indentations and missing closing curly braces) which makes your code a lot harder to read, and spot errors in. Please consider cleaning up the code, both for your own future sake (increasing readability and maintainability), and for anyone else who will be reading it. This makes it a lot easier to debug.

Looking forward to resolving this issue together!

Best regards,
Karl

Thanks for the tips I make it clear next time.

 I try breakpoints and find the exact line where the error and come back.

Thank you for clearing up the code.

Could I ask why you have included the 'clock start' section?
The SoftDevice restricts access to the CLOCK peripheral when it is enabled, which is likely the cause of these fatal errors. As mentioned in the SoftDevice's hardware peripheral requirements, restricted peripherals should only be accessed by the application through the SoftDevice API when the SoftDevice is enabled.

The relevant exempt reads:

Table 1. Hardware access type definitions

Access type	Definition
Restricted	The hardware peripheral is used by the SoftDevice and is outside the application sandbox. When the SoftDevice is enabled, it shall only be accessed through the SoftDevice API. Through this Application Programming Interface (API), the application has limited access.

The CLOCK peripheral is classified as restricted when the SoftDevice is enabled.

If you tell me more about the functionality you are looking to implement with these lines, or why you have added them in the first place, I could maybe come up with an alternative approach, that will be OK with the SoftDevice.

Best regards,
