Hrm, once the TBeams go to sleep, and say you had your phone / tablet in airplane mode, or turned off or out of range or it was disconnected because the TBeam went to sleep… how do you reconnect? As long as 1 device is still connected to a TBeam, and you send a message, it seems to wake the other units up and display the message on the screen. Most times the other droids reconnect and display the new message. But Im having a hard time getting them to reconnect without pressing the middle button on the TBeam, sometimes having to force stop the Android App.
Is the BLE fully sleeping or does it sit and listen for a connection request like the TBeams seem to be sleeping waiting for a message?
