product detail
Product introduction:
1. Two styles, patch style and bottom style. The patch model has a voltage of 3.3v, and the model with a bottom plate has 6 pins, which supports 3.2 6V voltage and TTL level.
2. The master and slave body can be set by AT command. One master and one slave, automatic connection after power on.
3. Lower power consumption, shutdown current is as low as 0.3uA. Sleep current is 4.5uA, low power consumption mode is only 75uA, which can be found and connected.
4. Higher speed, serial 0 baud rate supports 1200 230400.
5. It cannot be directly paired and connected with the built-in Bluetooth-compatible of the PC and the built-in Bluetooth-compatible of the mobile phone. It needs to be connected through the BLE APP or applet without a pairing code. This is determined by the BLE protocol. This is the case for all BLE Bluetooth-compatible modules. product problem.
6. The transmission distance in an open environment is 40 meters.
7. HC-42 UUID: search UUID: FFFO, service UUID: FFEO, transparent data UUID: FFE1.
