Hi!
I have 3 moteino boards, 2 are identical (on same order) moteino M0 and one moteino-usb R6, alle having the same radio modem.
Loading the same node application on the two M0 boards give different results. On one board, the sending will not start because the RSSI report a level of -3, while the other M0 runs the sending according to the printed output but my spectrum analyzer shows no RF signal. This M0 report the RSSI level of -103 which is probably more correct.
Compiling and loading the same node application on the moteino-usb gives identical result as the first M0, that is a RSSI level of -3
I wonder if any of you can tell me what is wrong. Are the modem chips damaged?
-3 is a rather strange RSSI, -103 is maybe the real number but somehow it gets truncated.
They are tested before shipped and loaded with a sender sketch which ensures they are functional, so I believe the sketch/code is probably the problem.
What sketches are you using?
There is a patched RadioHead library on this page, which works with all Moteinos, and I recommend starting with the rf95_client and rf95_server examples.
Match the settings to your hardware radio (frequency etc). Make sure you have antennas soldered (and oriented perpendicular to the board for optimal performance if they are wire monopoles).
Thanks for your reply!
I think I found it, it is named RadioHead-1.121.zip Is this driver patched such that the default constructor has the right pins (chip select and interrupt) for *all* Moteino boards?
Regards
Yes
