How to synchronize NRF52 ?

[Ronan]

how to synchronize multiple NRF52 them? Should I use a router? What route do you recommend for development?

Otherwise many people tell me that the Bluetooth has a very low focused, she has a good chip nrf52 distance with bluetooth?

Thank you very much :)

Ronan,

If you use nRF52 and the BLE softdevice then each device can connect up to 8 devices (configurable as central or peripheral). It can connect to a smartphone or any other BLE device. If you only need a router for example in IoT use case where you need to translate Bluetooth Smart traffic into IPv6 traffic, else you do not normally need a router.

The bluetooth is working in 2.4GHz frequency range. But the signal can be interfered, diffracted, reflected or absorbed, so practically it will give you a good range of 30-40 meters depending on your surrounding. (in open space it should ive a range of about 70-80 meters). This has to do with the frequency band Bluetooth Smart operates and also the signal bandwidth of the RAIDO.
