I need to connect multiple Bluetooth 4.0 devices to the arduino.
There is a "master" module, which is an arduino + WiFi + HM-10 BLE module.
Then there are "slave" modules, which are made with an arduino + sensor + HM-10 BLE module.
I have one master module and multiple slave modules, and I want to read the sensors data of the slave modules from the master module, but keeping the connection open with both slave modules simultaneously.
Is that possible? Thanks!
