Resolved! I would like to develop a piconet using STM32 BluenRG 2 DK by setting up one master device and multiple slave devices. Every slave is connected to an analog sensor and the master should discover the slave, connect and receive data and disconnect.
STEMEVALIDB008 V2 is the board I am planning to use.Link: https://www.st.com/en/evaluation-tools/steval-idb008v2.html
