Problem connecting of EByte E32, bad config response

[John]

I put the line of code you suggested:

#include “Arduino.h”
#include “LoRa_E32.h”
// #define LoRa_E32_DEBUG
#define LoRa_E32_DEBUG

and got the following:

It looks the same as the previous output.

Thanks for your help,

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.

Any clue as to the problem?

Hi John,

put all in DEBUG by uncommenting this line

// #define LoRa_E32_DEBUG

and check that the Serial is correct in this line

#define DEBUG_PRINTER Serial

Bye Renzo
