  • The Bangle's Bluetooth range isn't that great so 5m max for connections is about what I'd expect. However I'm very surprised it keeps dropping out - usually there are a certain amount of retries before a connection fails, so even if it's an unreliable connection it usually stays up.

    Unfortunately what @fanoush suggests with NRF.setTxPower is already done internally, so it's already at max power. I guess there may be a way to increase the amount of dropped packets it'll tolerate before trying to close the connection.

    But it is possible it's something to do with high radio traffic/noise in your area as @fanoush points out.
