clarification regarding ADC and radion communication

[chandhumallireddy]

Hi everyone,

I am working with the STM32-NUCLEO-WL55JC2 board and I want to transmit ADC values over LoRa radio. Since this is a dual-core MCU (Cortex-M4 + Cortex-M0+), I would like to clarify the recommended implementation approach.

My goal is:

• Read analog data using ADC

• Send the ADC values via LoRa communication

• Possibly use the dual-core architecture efficiently

My questions are:

1. Is it recommended to run the ADC acquisition on the M4 core and the LoRa/Sub-GHz radio stack on the M0+ core?

2. What is the best method for sharing ADC data between the two cores (IPCC, shared RAM, mailbox, etc.)?

3. Are there any reference examples in STM32CubeWL that demonstrate a similar workflow (sensor data → radio transmission).

4. Are there configuration considerations in STM32CubeMX/IDE when enabling ADC together with the radio stack?

Any guidance, documentation references, or best practices would be greatly appreciated.

Thank you!
