ADC with BLE onSTM32WBA

Hi,

I want to implement a simple application: ADC conversion and transmit the data via BLE. I achieved to do it on stm32wb15cc development board, but I have problems when trying do implement it on my custom board with stm32wba54. In the codes, I basically do the followings:

 

1. Start ADC conversion with DMA, triggered by timer.

2. When buffer is full, in conversion complete callback function, register BLE transmission task in sequencer to tranmit buffer data.

 

On my stm32wba54 board, the buffer won't start filling. I suspect that it's because in wba series, internal temperature sensor needs to enabled for RF calibration and it keeps conflicting with my main ADC channel. How couId I deal with that?

 

Thank you!
