Problem solved. As Sara has noted before, the AltSoftSerial can only use pin 6 on the Mayfly for receiving and pin 5 for transmitting. So, while the sketch worked with Software Serial as shown above (
Problem solved. As Sara has noted before, the AltSoftSerial can only use pin 6 on the Mayfly for receiving and pin 5 for transmitting. So, while the sketch worked with Software Serial as shown above (and would have worked by defining pin 6 for transmitting and pin 5 for receiving), my pairing of the sensor rx and tx wires to the Grove jack was wrong. See lines 17 and 18 above; I swapped the wiring from the sensor to the Grove jack and now get data from the sensor. This is what the portion of the sketch in question should look like to work with AltSoftSerial:
