Bluetooth Remote Control to send multiple information to microcontroller. The purpose of the app is to interact with hardware like ESP32, Arduino, Raspberry Pi ... Only the Bluetooth SPP Profile (RFCOMM) is supported. The first optional information is a channel, which has the range from 0 to 3. Afterwards 3 positions are handled as bytes or text. The range of the positions (power) is between -100 and 100. UP: [channel], 0, power, 0 DOWN: [channel], 0, -power, 0 LEFT: [channel], -power, power, 0 RIGHT: [channel], power, power, 0 MIDDLE: [channel], 0, 0, 0 Byte Mode enabled: Optional channel and 3 positions are transfered as bytes Byte Mode disabled: Optional channel (seperated by colon) and 3 positions are transfered as text seperated by comma (ended by \n) Sense: On Release automatic return to zero values: [channel], 0, 0, 0 Channel (Ch.): Enable optional channel information (first byte or text seperated by colon) Power: Slider from 0 to 100
