5. Function

5.1 Roles

There are four roles: master, slave, observer, salve and master as one.

The master module/slave and master as one connects to other Ebyte Bluetooth models. Up to 4 slaves can be connected to it.

Transparent advertising and format transmission are available. Both manual and automatic connection are allowed.

The slave module connects to other Ebyte Bluetooth models, only one connection is allowed. Only transparent transmission is

available for slave.

The observer is only used to print information about the ble device around the module and cannot be connected.

Note: BLE is initiated by the master, and the slave responds. Where it is located manually, the automatic connection

function is only valid for the master and master-slave integration.

The internal level of the pin is self-latching. It internally pulls up for high level and pulls down for low level.
