[Introduction]:E104-BT53C3 is a serial-to-ble module based on ble protocol version 5.2. It has the characteristics of high temperature resistance, small size, low power consumption, long transmission distance, and strong anti-interference ability. It works in the 2.4GHz frequency band. The ble module is a car-grade ble module developed based on Silicon Labs' EFR32BG22C224F512IM40-C chip. It can be used for a long time in an environment of -40~+125°C. The ble module uses common AT commands, and the operation is simple and fast. ble modules can be widely used in smart wear, home automation, home security, personal health care, smart home appliances, accessories and remote controls, automobiles, lighting, industrial Internet, smart data acquisition, smart control and other fields.

9PA03I/0GPI0
10PA080Indicates the connection status of the slave (including the role of Beac0n); the pin outputs a low level after the connection is successful; the output is a high level after the connection is disconnected
11PA070Indicates the connection status of the host; the pin outputs a low level after the connection is successful; the output is a high level after the connection is disconnected
12PA06RTS(Standard hardware flow control Require T0 Send) module output signal, when it is high, it means that the serial port of the module is busy, and the MCU is not allowed to send data to the serial port of the module, and when it is low, it can send data to the module.
13PA05CTSStandard hardware flow control (Clear T0 Scnd) module input signal, when it is high, it means that the MCU serial port is busy, the module will not send data to the MCU serial port, and when it is low, it can send data to the MCU.
14PA04REST0REInternal pull-up. Falling edge, and then keep the low level for at least 5 seconds, all parameters will be restored to factory settings and the module will automatically restart
