There is no limit in sending bytes with HM-10.HM-10 has the latest 4.0 Bluetooth technology.This helps to understand the current situation of the Bluetooth device. There is a button on the device to break the connection just like a BRK pin. To disconnect the connect apply the LOW input signal on it. There will a HIGH output signal at state pin for established Bluetooth connection otherwise it will be at a low.īRK represents the break, which helps to disconnect the connection of Bluetooth with another module. This pin is just for state representation. TX will send the data from the Bluetooth to the Arduino/microcontroller.
RX will help to receiver the data from Arduino/microcontroller. HC10 communicates follows the UART communication protocol for data sending and receiving.
