Four Bluetooth modules (slaves) should connect to a fifth Bluetooth module (master) and send data to the master.
The Bluetooth module is a BL652 from Laird.
I have already started with the code but can not transfer any data.
This is the primary task and very kurzfistig to do.
If a stable connection is established and the data exchange is working, the following can be done as a secondary task:
- to save energy, the slave should lie in sleep and be woken up by the master.
