Yes Pebble OS is now open source, however I think adding RSSI might only work on newer devices, since classic pebbles are just Bluetooth and Bluetooth le. Though they may have Bluetooth le as a part of pairing?
Still a fun experiment and a good way to see why Bluetooth headphones actually are as reliable as they are.



















If I am right I don’t think Pebble watches has Bluetooth LE, it has the ability to broadcast itself but once connected uses Bluetooth. The OS doesn’t expose LE so I don’t think getting the signal strength is possible
