HET UART pass through Firmware functions Operating Instructions5.1 Transparent Mode and Command ModeModule can operate in transparent mode and command mode.Transparent mode: In this mode, users don’t need to think about the complex Bluetoothprotocol application, you can complete the development of products quickly. In this mode themodule will automatically transmit the received UART data to the bonding mobile device throughBluetooth. also it will automatically transmit the received Bluetooth data to the MCU throughUART. For product development, the user is responsible for the main MCU firmware design andintelligent mobile device APP design.Command Mode：In this mode, the module can be controlled through specific serial ATcommands, for details please refer “H&T BLE Modules Programming Guide”5.2 Switch between two modesThe module can be switched between 2 modes through PIO7,when PIO7 is low, CommandMode is enabled, when PIO7 is high, Transparent Mode is enabled.5.3 Sleep and WakeBefore sending serial data to the module through UART, the PIO1 need to be pulled down to

When the user’s MCU monitors the module PIO12 has been pulled down, thismeans module has been successfully woken up, then the data can be sent at this time. during datatransmission, PIO1 must remain low, after data transmission is completed, the PIO1 pin need to bepulled up, then the module goes to sleep again to reduce power consumption.Once the module receives data from another end BLE device, the data will be automaticallyforwarded to the MCU, also the PIO10 pin will be pulled low to inform the MCU to receive data.During data transmission PIO10 pin will remain low. After all serial data transmission is completed,PIO10 pin will be pulled up.6.
