GPIO not working with SD

[Gautham]

Hello,

I have configured a 1 ms timer (Timer 2) interrupt. I am just updating some static variables for reference in the 1 ms interrupt. Everything seems to be working fine here (SD enabled). However I tried to toggle one of the GPIO pins in the 1 ms interrupt routine every 6 ms. Looks like this does not go well with SD. The control is in SD and is not returning to any one of my functions. I am not sure what the problem is. After this the SD stops broadcasting and nothing works. After I reset the controller via debugger it starts broadcasting and the same thing repeats.

Are there known issues in this regard? If not then can anyone let me know what might be the problem? I am not sure if I have given sufficient details. If not do let me know.

I am using: SD: 7.1 SDK 6

Thanks in advance!

What you are trying to achieve is basic and that should work otherwise there would have been a lot of reports here regarding that. I have verified this on SDK 7.2 with just one advertiser and there were no problems with the gpio. I verified even with 0.1ms timer interrupt and it just worked fine.

post your code here and I can check for you.

Hey Aryan,

Thanks for your time and inputs. I have updated your code as per your suggestion. The port I am toggling is basically connected to a Piezo buzzer. As stated the buzzer starts beeping upon starting the device. Upon BLE connection or disconnection the buzzer stops and then the device stops broadcasting too. I have kinda reached a dead end here. Is it possible to share your project? I would like to flash your s/w and check the behavior with my device. Thanks!
