Connections are good.
4.92 VDC to GND at the transmitter, not polarity reversed.
No signal detected by the RFToy.
Have not tried the speaker trick.
The time stamp of the opensprinkler file agrees with when I compiled it.
Still no workie
I wonder if I fried the transmitter. I’ll try it in the RFtoy tomorrow.
Other than that one change in defines.h, was there anything else in the 2.1.3 code that deeded changing?
