Raspberry Pi 3 BLE Chip limitations

Hi all,

I’m planning to use 20 RuuviTag for temperature measurements with one raspberry pi 3 B+, is there any limitation on the number of BLE devices connected to the raspberry bluetooth chip ?

Thank you for your answers.


RuuviTags are in broadcast mode, i.e. no connection is established. This means that there is no hard limit on how many RuuviTags your RPi can hear, however at some point the interference of other tags broadcasting will lead to packet loss. 20 should be fine, and if you have issues you can flash in a firmware with less frequent broadcast interval so there is less interference.

Thank you for your answer, that’s what i was wondering ! :smiley:
