Hello,
I have used the stock Moteino FTDI Adapter many times but its not working reliable any more. I use the vanilla Node sketch.
1. I can burn the sketch
2. I can start the sketch and see output in the serial monitor, sometimes the code runs 10 x Times slower than normal
3. Send functions of Moteino will not work
But if I unplug the FTDI Adapter and replug again than in 1 of 5 cases send works again. Sketch will also work when running independend from FTDI Adpater without problem
I just ordered 2 new FTDI Adapters.
I think I fried the adpater in some way that the reset is somewhat broken and the RFM69 will not be reseted correctly as well.
Did anybody had the same Problem?
Now I'm "debugging" with the LED.
Best Regards,
René
Possibly the mating header has a loose connection?
Do you have another FTDI-Adapter to test with so you can definitely tell the other is bad?
Or another Moteino to test with this FTDI to see if programming that Moteino has the same effects?
Hi Overlord,
Intermittent problems I experienced while programming turned out to be cables.
Let us know how it goes and what you figure out.
Good Luck
Yes, poor cables that are not shielded or have lossy connections can cause this and other issues.
I would recommend always approaching this type of problem by trying to isolate the problem.
So in your case the cable also has to be eliminated as a cause.

What was it about the bad cables that made them bad? Too big a voltage drop? (e.g. Too long? Wires too thin?) Or was it something else?
QuoteWhat was it about the bad cables that made them bad?
Regular use broke the stranded wires causing intermittent connections.
The cable would work fine in a particular position but flex it near the
mini USB and it would no longer connect.
OK I did another test this morning and evening and now its working.
I use XUbuntu 16.04 with Eclipse Plugin from Sloeber http://eclipse.baeyens.it/
I use USB 3.0 ports. Maybe some other process was dealing with my USB COM Ports in some way.
Maybe some EMI problem yesterday I had my MacBook Adapter and Printer powered on - in near range of the board. It's really unbelievable.
Anyway invest in the addtional FTDI adpaters is good.
Thanks for the suggestions.
