ADC + ble connection

[frank zhang]

I am using nrf51_sdk_v6_0_0_43681 and s110_nrf51822_7.0.01 wiht nrf51822, and I modifiy code based on ble_app_uart.

Here I am trying to launch a continous ADC sample with a repeated mode timer, the timer interval is 1ms or 2ms or 4ms. Meanwhile I disconnect and conect my cellphone(Samsumg Notes 3) with nrf51822 board. Serval times later, I found that the nrf51822 system should be crashed,because my local uart can not be input and ble has no advertising.

What is the problem?

Thanks

Frank

Hi Frank

Take a look at this example code on Github where the ADC is continuously sampling when the softevice is advertising/connected. As you describe you problem, I suspect the problem might be the priority of your ADC interrupt handler, you must explicitly set the priority when you initialize the ADC
