hi i'm new in bluetooth mesh technology i have some question about nrf5 i want to build a system with 500 sensor any one can help me please ? which chip can i use nrf52832? and how ? how many nrf52832 can be in one blu mesh ?

hi i want to build a system with 500 device they send some data to controller wireless how can i do it with blu mesh ?

which chip should i select ? i prefer nrf52832

and i need any thing else ? another board ? or some thing

Yes, nRF52832 is suitable for this task. You can also consider nRF52840 as powerful variant with more memory space, but take in higher price. To start developing I recommend you to hava a DevKit: nRF52-DK (development kit with nRF52832) or nRF52840-DK (dev kit with nRF52840, if you will select nRF52840 chip). You need DevKit to program and debug your firmware. Probably you will need 2-4 kits, because you working with mesh, but it depends of your sensor nodes, maybe even 1 will be enought. Also I recommend to find some solutions as nRF Connect but for mesh (I'm not sure that nRF Connect support and working with BLE Mesh).

You can download and learn BLE Mesh SDK - here

Also take a look in the infocenter about this SDK, there you can also find some basic about BLE Mesh - link

In mesh you can add up to - 32767 nodes.

Note that the Mesh does require a lot of memory:

hi

how can i measuring the size of space i need to ?

i have experience with microcontrollers a lot

but about blu not at all

Hi,

You can see the flash and RAM requirement for the Mesh examples here.
