NRF52832 mesh problem

lawalan

Hello everyone,

I am developing a temperature and gas sensor for indoor environment monitoring. Due to the limitation of the bluetooth transmission range, I hope to add a "repeater" inbetween the sensor and my mobile phone to extent the connection range.

So the case is like this...

I connect my phone with the sensor, reading all the data when i am in range. When I move further apart that exceed the connection range, the sensor will automatically switch to send data to the "repeater" and the "repeater" will be connected and send the data to my phone.. so that i can still receive real time data.

May I know such logic would be solved by using mesh? and may someone explain how to do it?

Many thanks!!!!

    Hi Alan,

    There are different approaches you can take to implement a solution like this depending on how many relay nodes you need and the current consumption requirements of your application.

    One way to solve this problem if we are talking about a limited amount of relay nodes, is setting up BLE relay devices between you phone and your sensor, take a look at the relay example we have here.

    If you are talking about a network with multiple sensors and relay nodes (i.e. inside a building) mesh is certainly the way to go. Any mesh device may be configured to act as a relay node and to automatically retransmit messages. The downside with using mesh is the that the current consumption of the relay nodes will be high, since the devices must continuously keep their radio in listening mode, so this is something to consider.

    If you want to learn more about how mesh works you can take a look at the following blog posts about mesh:

    To start developing for mesh you can download the newest SDK for Mesh and take a look at some of the examples we provide, i.e. the light switch example.
