For Bloß devices, there are four common working modes of Bluetooth -Module:

1. Master mode

Feasycom Bluetooth low energy module supports master mode. Der Bluetooth -Modul in the master mode can search the surrounding devices and select the slaves to be connected for connection. It can send and receive data, and can also set the MAC address of the slave connected by default, so that the module can find this slave module and connect as soon as the module is powered on.

Notiz: If you want to perform one-to-one transparent data transmission, you need to use our master device to connect our slave devices. We do not support the connection of slave devices from other companies (because the built-in transparent transmission protocol is not compatible). Jedoch, our slave devices support the standard Bloß Protokoll, and users can develop their own.

2. Slave mode

Der Bluetooth -Modul working in this mode can only be searched by the host and cannot be actively searched. Nachdem das Sklavengerät mit dem Host verbunden ist, Es kann auch Daten mit dem Host -Gerät senden und empfangen.

Feasycom’s new Bluetooth 5 Modul: FSC-BT616, supports Bluetooth master-slave mode, which can be used as either a master or a slave. The two working modes are easy to switch.

3. Broadcast mode

In diesem Modus, Die Bluetooth -Modul can perform one-to-many broadcasting. The user can set the data broadcasted by the module through the AT instruction. The module can continuously broadcast in the low power consumption mode. It is used in applications with extremely low power consumption, small data volume, and unidirectional transmission, such as beacons, billboards, Indoor positioning, material tracking, usw. Such modules include Bluetooth 5.0 modules: FSC-BT616, FSC-BT630; Bluetooth 4.2 modules: FSC-BT909.

Notiz: Der Feasycom Bluetooth module comes with Leuchtfeuer Protokoll. Users only need to match a standard 3V button battery or a pair of AAA batteries, and then set the parameters by AT command to become a Leuchtfeuer Gerät.

4. Mesh network mode

In diesem Modus, multiple modules can be simply added to the network. Using the star network and relay technology, different networks can also be interconnected. In the end, a large number of Bluetooth -Module can be interconnected through a mobile phone or tablet or direct manipulation.
