Handle multiple nRF51822 devices on the same room

Hello,

I am planning to develop a system where there are 16 bluetooth LE devices (nRF51822) each one sending/receiving data via Bluetooth LE (~30 kbps) to/from an access point (or PCs with dongles).

Someone tested a system like this before? Do you think is really possible to make it works in a proper way on the "real world"? What kind of problems I have to expect (collisions, packets lost ...) ?

Please take into account also that:

  • the 16 devices will be placed in the same room, close to each other.
  • to achieve 30 kbps I have to use a "non-acknowledged" data transmission

Thanks a lot

  • Hi there,

    This will of course vary wildly depending on several factors, but I can tell you that I have been in extremely crowded rooms in terms of 2.4GHz devices (sometimes 100+) and BLE has kept up without serious problems, so 16 devices does not sound like it should be a problem in principle.

    About the data rate, that will be mostly limited by connection intervals and the ability of your master (the PC) to keep up with 16 slaves and send fast enough, the slaves themselves should have no problem at all with that sort of data rate.
