I am working with amplifier which supports SPI protocol and that amplifier output I am using as input to ADC pin of nrf52832.

So I am getting ADC output via SPI protocol and can see output on Teraterm.

Now the issue is I want ADC values on Bluetooth device. but when I call SPI function BLE stops advertising and when SAADC function is called BLE gets advertised but no output, I wont get ADC values on Bluetooth device. So how should I resolve this issue.???? Where I want SPI and SAADC function to be called simultaneously in main program and I can get output on Bluetooth device.

Do you use interrupts in SAADC and SPI?

If so, please check their priorities. Also, please attach the debug log when you enable the SPI function.

What do you mean by that?

Is it just the BLE Advertising that stops? Do other things keep running? Or does the whole system crash?

[quote userid="80924" url="~/f/nordic-q-a/49736/how-to-send-saadc-values-to-bluetooth-device"]please look after the code i have attached[/quote]

But what debugging have you done to find out what's going on?

Debugging is a key skill and an essential part of any sort of development - you can't just expect others to do your debugging for you!

Please suggest how to send ADC data to ble device via SPI protocol
