Mesh working status

lgs

Hi There,

I have a question. Why does the BLE MESH need to keep the radio running constantly?

Regards,

    Hi,

    Bluetooth mesh is a flooding mesh protocol, where nodes send packets in advertisements in an uncoordinated manner (no timing), and spend the rest of the time in RX in order to listen for those non-timed advertisements from other nodes. That means a normal Bluetooth mesh node is in RX most of the time, and when it is not in RX it is in TX.

    In addition you have Low Power Nodes, which are sleeping most of the time, and wakes up only to do TX or to poll their Friend node for incoming messages.

    There is also the option to connect to the Bluetooth mesh network over GATT, in which case you get a normal BLE connection with a GATT Proxy node from the network. The GATT Proxy node is then a normla mesh node (using the radio most of the time for RX) but in addition allows incoming GATT connections.
