Audio transmission

Dogukan · ‎2023-11-05

I have a STWIN SensorTile Wireless Industrial Node development kit ( STEVAL-STWINKT1B). I installed this code (https://github.com/STMicroelectronics/fp-sns-datalog1/tree/main/Projects/STM32L4R9ZI-STWIN/Applications/HSDatalog) to the board. STWINKT1B has BLUENRG-M2SA (BLE) module and analog, digital mems microphones (IMP23ABSU, IMP34DT05). I want to transmit microphones data to my computer using BLUENRG-M2SA (GATT characteristic). A Python code will run on the receiving part (my computer) to receive the microphone data. Is it possible to do this?. How can i do?

Hello @Dogukan

DATALOG1 is not streaming data via BLE, but only commands used to control STWIN sensors, tags and start data streaming on the SD card.

What you are proposing is feasible, but you must manually modify both firmware and python sdk.

Best regards
