BLE Mesh Range

Urvisha Andani

I am Currently under process of evaluating various modules for implementing BLE Mesh, Had few concerns regarding the same, would be great if someone can clarify upon them.

1) In Nrf Modules weather BLE Mesh in Implemented upon BLE4 or BLE5

2) Max Transmit power that can used in MESH Mode

3) In Mesh Mode are Le Phy coded configuration are available. particularly looking at 125 bp/s.

Ran into  range issues with BLE solution from another vendor that i was testing (Normal mode was great,but MESH mode had limitations), so thought of clarifying this questions before starting tests with NRf solutions.

Any redirection towards an In-Depth article would be of great help too.

    Hi,

    1) BLE mesh is based on BLE 4.0. It is compatible with BLE 4.0 and higher (this includes BLE 5.0) but does not implement any features of BLE 5.0. You won't be able to use 2Mbit and Coded PHY with Mesh, as these are BLE 5.0 features. The Bluetooth mesh speficication is defined by the Bluetooth SIG group and can be downloaded here.

    2) The max transmit power will depend on which SoC you choose. The max transmit power for the nRF52840 is +8dBm. For the nRF52832 is +4dBm.

    3) As I said, coded PHY is a BLE 5.0 feature and is not implemented in the BLE mesh specification.

    And if you want more information about our BLE mesh solution have a look a these pages for more information:

    Basic Bluetooth Mesh concepts

    nRF5 SDK for Mesh architecture

    Best Regards,
