@jes OK, so the clock source change does not help. Here is another one, it disables larger MTU negotiation. This makes communication slower but more compatible to old devices and also the connection negotiation is simpler. Flashed it to my watch via the Firmware Update https://banglejs.com/apps/?q=firmware and it still works (don't have C3 board here).
