I have switched my daily driver bangle to my second one and had massive problems with the Bluetooth stability to my HRM belt, connection loss about once every 2 minutes. After finding this I set the expected accuracy in the firmware all the way up to 500ppm and it seems much better. Comparable to the older Bangle. Both had the same firmware and exact same software (brought over via backup/import).
Is this possibly this timer accuracy thing? How can I prove this theory, is comparing clock drift between the two Bangles over 24 hours good enough for this?
