Problem on reading data from GPIO pins when device is advertising...........

Hello,

I am using nrf52832 board, having SDK 15.3.0 in Segger studio IDE, using window10.

I am trying to read from ADS1232 IC,

Connection: 

DOUT - P0.11

SCLK - P0.12

A0 - P0.26.

Here when i am not enabling advertising, i am getting correct values as expected from the pin.

but as soon as i am enabling advertising, my data is getting changed.

Regards,

    Are you able to get an error code at all? P0.26 is described as a pin located near the radio in the product specification and is recommended to be used as a low drive, low frequency I/O only when the radio is active. The activity of them is likely interfering with each other. I suggest you use another GPIO to see if anything changes. P0.22-P0.31 are all "located near the radio, so avoid using these pins.

    Best regards,
