Mesh like network base on BLE connection， BLE and long range conexist issue.

[jhc]

Hi, All

In our product development, we finally found that our products need to work in long range mode to improve the communication range, and keep the connection with mobile phone at the same time. so my first question is, is it possible to make the BLE 1M conexist with long range mode?  Is there any example and related document for me?

We connect our products with each other by a start network base on BLE connection:

but we have more intresting in the MESH like network which was showed in webinar video " introduction-to-blue-low-6-1-video': , and is there any example and document for reference?

Thank you very much!

Hi

The S132 and S140 SoftDevices allow you to run up to 20 connections simultaneously, and you can use different PHY's on the different links if you want. 

In other words it is possible to have one connection running in 1M mode, and another connection running in long range mode. 

We don't have any examples showing how to do this type of connected Bluetooth mesh unfortunately. 
We have an implementation following the Bluetooth mesh standard, but this is based on advertise packets and not Bluetooth connections. The advantage of this is that it is easy to support a large number of nodes in the network, but you get higher current consumption and lower data rate than you would with a connected mesh implementation. 

If you want a connected mesh implementation without having to spend considerable development time to create one from scratch you might want to have a look at the Wirepas mesh implementation:

Hi, Torbjørn

Thanks for reply.

I will study on the Wirepas mesh later, hope that would meeting our requirements.

As you mentioned: it is possible to have one connection running in 1M mode, and another connection running in long range mode, is there any example for this for reference.
