Hi, I have the emonTx 3.4.1, supplied without RF module as I have a nanodeRF with an 868 MHz radio module that it will be communicating with. RF module supplied separately and now soldered on is the RFM69CW, 868 MHz. In the sketch, emonTx V3.4 Discrete Sampling V1.80, define RF69_COMPAT has been set to '1'.
The sketch is executed up to, 'rf12_initialize(nodeID, RF_freq, networkGroup);'. I have put a Serial.println immediately before the rf12_initialize line which is output to the serial monitor, and another Serial.println immediately after the rf12_initialize line and this is not output to the serial monitor.
So, is this bad soldering on my part, or is there another possibility? I have soldered the nanodeRF, emonGLCD and emonTx successfully so not a complete novice, but it is possible that I have not done the soldering properly. Or is there another possibility I am missing? And is there a way to check my soldering, and or the radio module?
Any suggestions will be much appreciated.
Re: emonTx 3.4.1 red led staying on, not mismatched sketch and radio module
It certainly looks as if the radio module is not initialising, and the sketch is hanging waiting for it.
Silly question hopefully: Is the radio module the right way round? See "RFM Radio Modules - Identifying different types" in Building Blocks.
Do you have the latest JeeLib?
Re: emonTx 3.4.1 red led staying on, not mismatched sketch and radio module
Hi Robert, thanks for the suggestions. Yes, radio module is the right way round - checked with the reference you gave. I have the latest JeeLib from https://github.com/jcw/jeelib. I have checked my soldering by testing continuity from each contact on the circuit board and the corresponding contact on the radio module, being careful not to make a direct contact with the probes, although that was difficult. All test OK. In desperation I have also checked continuity across the contacts on the the radio module. Don't know what I should be getting and the only one where I don't get continuity to any of the other contacts is ANA.

And the solution was get my eyes tested! Wearing my new pair of glasses I then re-did the soldering and now all works well. :)
