Chip selection is used as a Bluetooth mesh host

[role_2099]

I want to use the nrf5x to develop the host/gateway of bluetooth mesh, may I ask which model is more suitable, which model currently supports the most mesh nodes?

And which SDK library is used to develop Bluetooth mesh now?

Best wishes and regards!

Hi.

Could I ask what kind of host/gateway you are developing?

You can use both nRF5 SDK for Mesh or NCS to develop BLE Mesh applications.

Hi Joakim,

My gateway converts the Ethernet (STM32) to Bluetooth (NRF52840), they connect through the serial port, and finally control the Bluetooth mesh lighting on the web page.

Best wishes and regards!

Thanks.

I want to ask some questions about this;

may I ask which model is more suitable

Which model is more suitable for what? Any particular task you are looking for?

 

which model currently supports the most mesh nodes

With "the most mesh nodes", are we talking about a physical number of nodes? In that case, that wouldn't depend that much on the model itself.
The limitation on how many nodes you can have, is more related to how the network is designed, how many nodes you want, how much data you want to send etc.

Hi Joakim,

Is there an estimation method? I send a 16-byte command and use nrf52840. Can the maximum number of mesh nodes be calculated?

Best wishes and regards!

Sorry about the delay. 

There really isn't any valid, fixed estimation on how many nodes that is "acceptable" for a network.
There are many factors that would affect the network; physical obstacles, range, area, noise from other sources etc. Packet collision when there are too many nodes in a confined space will affect the network etc.

But there isn't really a real upper limit of the number of nodes, the theoretical max number is  32768 nodes (due to the available number of addresses).

The available flash on the provisioner node could also be a factor, as the provisioner have to store some data for each new node in the network.
