FAQ

Can I use BL652/BL654 pair with BLE tag?

No. it is not possible as BL652/BL654 is NFC tag as well. You can make it to pair with a phone. The phone can provide the NFC energy field to energize the BL652.

Is BT 5.0 extended range feature related to higher power on newer modules like BL654, Sable X-R2?

Actually the extended range is achieved with slower transmission bit rate which let the radio emissions can be correctly received at a longer range. This data rate is reduced.

What's the total number of concurrent connections?

The BL652/654 can do 7 (outgoing)+1(incoming) connections. But it is not possible to do 2 incoming, as peripheral can only 1 incoming, per the BLE spec.
