I have an Arduino Uno R3 using +5v connected to a RFM12B-S2 board with a custom pcb (attached). The pcb is basically the same as jeelabs and sparkfun's boards and is powered by +3.3v with voltage dividers for the 5v inputs. I have imported the jeelabs library (RF12 and Ports) and uploaded RF12Demo and flashed/reflashed the Rfconfig() and set groups/nodes/frequencies. I also have a +3.3v breadboard Arduino connected to a similarly (all voltage dividers bypassed) wired RF12B custom pcb. According to everything I've read, I should now be able to upload the pingPong sketch and these things should just work. The problem is they aren't working, at all.
I have checked both boards for voltage and the proper voltage. Everything looks fine. I've uploaded sketches that are supposed to flood the airwaves, but a scanner tuned to 433MHz gets nothing. I disconnected the RF12b modules from the Arduino and get exactly the same results on the serial monitor.
Here's typical serial monitor (looks the same with or without the RF12B module attached):
[RF12demo.8] D i4* g212 @ 433 MHz
<nn> i - set node ID (standard node ids are 1..26)
(or enter an uppercase 'A'..'Z' to set id)
<n> b - set MHz band (4 = 433, 8 = 868, 9 = 915)
<nnn> g - set network group (RFM12 only allows 212, 0 = any)
<n> c - set collect mode (advanced, normally 0)
t - broadcast max-size test packet, with ack
...,<nn> a - send data packet to node <nn>, with ack
...,<nn> s - send data packet to node <nn>, no ack
<n> l - turn activity LED on PB1 on or off
<n> q - set quiet mode (1 = don't report bad packets)
Remote control commands:
<hchi>,<hclo>,<addr>,<cmd> f - FS20 command (868 MHz)
<addr>,<dev>,<on> k - KAKU command (433 MHz)
D i4* g212 @ 433 MHz
C i3* g212 @ 433 MHz
-> 1 b
Any suggestions on how to troubleshoot these?
