External ADC and BLE not able to work together

sorry for the delayed reply. Resolved the issue. It had got to do with the Digital filter not being able to reset properly before switching channels on the ADC.

Thank you.

Can you explain what is not working? Is the code stuck somewhere, does the device reset, etc.? If you could upload your code/project, it would be easier to help you debug and determine what is causing the issue.

Well, i am trying to isolate the issue.. not getting to anything. Yes, i have run the ADC without the BLE and it works.

ADC is utilizing SPI master interface and that is also running alright to me.

What debugging have you done to find out what's happening?

As it's an external ADC, you must have interface lines that you can look at - are they still behaving correctly ... ?

Surely, you could easily answer that by re-running your code that just has the ADC without the BLE - does it still work?
