WebbIf I2C clock stretches by a bounded amount, then lowering the I2C clock frequency can avoid the problem. Yes. I have 10 devices "in the field" at one location. Apparently the clock frequency (RC clock) of three of the modules is different in such a way that they end up "done" with the clock stretching in exactly the wrong moment.
