what is the maximum range to connect 2 NRF51822 devices with Gazell

[Tim]

Hello,

I was looking into Gazell and read that Gazell only allows pairing when Host and Device are in close proximity to each other. This range is about 30 centimeters. I was wondering if this range could be extended? and if this is possible what will be the range it could reach?

Thanks in advance,

Tim

The close proximity pairing feature in Gazell uses the RSSI measurement to detect if a device is in pairing range.

On the host side, the RSSI is compared against a threshold to decide if the device is in range, and is defined as

#define GZP_HOST_RX_POWER_THRESHOLD -64 ///< RSSI threshold for when signal strength in RX packet power is high enough.

If you want to extend the pairing range, you can adjust this threshold to fit your requirements.
