Using already delevoped BL Mesh library for 2,4 GHz long range radio?

[AndreasA]

I have been looking at the Mesh library for BLE communication and wonder how much work it would be for me to use the same library for a long range 2,4 GHz radio?

Is the mesh library included in nordic connect sdk based on some other open source Mesh library or is it self developed by NordicSemiconductor?

do you mean long-range BLE - or some other protocol ?

Nordic's licence terms only allow you to use their software on their chips

[AndreasA]

What i would like to accomplish is a Mesh communication with a distance range between 0,1 to 8 km. And on top of Mesh i would aslo like to implement MQTT-SN.

[awneil]

again, do you want to do that with BLE  - or some other protocol ?

you mean 8km (max) between nodes?

at 2.4 GHz ?

[AndreasA]

Some other protocol using 2.4 GHz, i dont think BLE can handle that range? Max 8 km between nodes is correct.

[awneil]

So what protocol did you have in mind?

Again, to use Nordic's code you have to use Nordic's chips - so it'll have to be a protocol supported by Nordic.

I'm not sure that anything at 2.4GHz (licence-free) is really going to be suited to such a long range?

[AndreasA]

I'm planing on using nrf52840 for this solution. And have now dropped the BLE mesh library and looking into building a mesh network using openThread. Not sure yet about the range.

Again, 2.4GHz is not a great choice for really long range - due to physics.

But one of the key features of a mesh is that it allows you to make many smaller "hops" to reach a distant point ...
