Operation Notice
Connecting WB822D Module to MCU (on the main board) via UART Interface as below:
The WB822D module will start BLE broadcasting using a name “ACEUni_UART”. Run an
App (such as “LightBlue”) on the phone you can scan and connect to the WB822D module.
The BLE_CONNECTION pin will be pull high to indicate that the BLE Connected is
complete. And now the data transceiver is viable between the WB822D module and the
MCU.
For the MCU the UART Parameters are：
Baud rate: 115200bps
Start bits: 1
Data bits: 8
Stop bits: 1
Parity Check bits: none
