Hi,
I use the HC-12 radio modules for send/receive data. These are very good for this type of thing,
The latest batch of modules, from 'can't remember' don't transmit properly.
Normally I can READ the output on a computer terminal, but also listen for the signal using a hand held radio, for checking.
This batch send an audible signal, but it isn't as 'bright' as the ones that work, so the data doesn't get received by the RX one.
Here's photos of both:
I've seen similar problems in the past, but not with this particular module.
Cheers, Camerart
