Googling Error

The error means the program is apparently receiving a very long FSK encoded signal with more bits/pulses than any currently known devices. However the Ambient sensors are nor FSK encoded, but OOK encoded instead. A likely cause is that your sensors are now sending their signal at the same time, disturbing the transmission of each other. As the sensors send at slightly different frequencies it is received as something that might look like a FSK encoded signal. It will happen as the periodic transmission from the sensors drift slightly and becomes overlapping, and it will disappear again as the timing drift further.
