I decided that the E32 might be bad so I ordered another. Rewired the ESP8266 and the E32, and retested. Still getting a Header of 0 0 0. Changed the ESP8266 with same results. I have another module that works fine. I printed out the following from the two modules:
Bad Module
LoRa Send
—————————————-
HEAD : 0 0 0
AddH : 0
AddL : 1
Chan : 2 -> 412MHz
SpeedParityBit : 0 -> 8N1 (Default)
SpeedUARTDatte : 0 -> 1200bps
SpeedAirDataRate : 0 -> 0.3kbps
OptionTrans : 1 -> Fixed transmission (first three bytes can be used as high/low address and channel)
OptionPullup : 0 -> TXD, RXD, AUX are open-collectors
OptionWakeup : 11 -> 1000ms
OptionFEC : 0 -> Turn off Forward Error Correction Switch
OptionPower : 10 -> 14dBm
—————————————-
e32ttl.available = 0
Success
Good Module:
LoRa Receive
—————————————-
HEAD : 11011100 220 DC
AddH : 0
AddL : 3
Chan : 4 -> 414MHz
SpeedParityBit : 0 -> 8N1 (Default)
SpeedUARTDatte : 0 -> 1200bps
SpeedAirDataRate : 0 -> 0.3kbps
OptionTrans : 1 -> Fixed transmission (first three bytes can be used as high/low address and channel)
OptionPullup : 0 -> TXD, RXD, AUX are open-collectors
OptionWakeup : 0 -> 250ms (default)
OptionFEC : 0 -> Turn off Forward Error Correction Switch
OptionPower : 1 -> 17dBm

Start listening!
e32ttl.available = 0
I switched the send receive sketches and got the same results. Good board provides a header in both cases, but neither ever reports e32ttl.available changing from 0.
