Hi cglkr97,
can you send the complete code PLZ.
Thanks Renzo

Thanks for your feedback, I’m happy that you have resolved your issue, in the next time I publish my shield, but I already worked on Arduino Mega one and surely I need to test It. If you like I need help on my site too.
Keep in touch Renzo

I check with my Arduino Mega, and my error is that I don’t use a correct RX pin as Arduino guide describe.

https://www.arduino.cc/en/Reference/softwareSerial

Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 14, 15, 50, 51, 52, 53, A8 (62), A9 (63), A10 (64), A11 (65), A12 (66), A13 (67), A14 (68), A15 (69).

Now I can send without problem and receive without problem on my Mega without any freeze.

I use this configuration

SoftwareSerial mySerial(11, 5);
LoRa_E32 e32ttl100(&mySerial, 3, 7, 6);

Now work correctly.

Please update the libray, uncomment
#define LoRa_E32_DEBUG

Enable debug mode on Lora e32 EByte library

And send me your log, I try to understand.

If you want to use HardwareSerial you must do like so
LoRa_E32 e32ttl100(&Serial2, 3, 7, 6);

I’m doing some test with mega and there is a problem, I’m going to discover in the next week.

I tested the example with a1 case but work for me and my Arduino UNO, I’m going to try with Mega.
Thanks for your patience Renzo

And please recheck your connection schema with the schema on the article not on Github library, and check that you have the last version of the library, I fix sometings 2 days ago.

Hi, I can’t check the sketch now, but please refer to my site, i update all the schema.
In the next few days I check all with my Arduino mega.
Thanks to write, and please wait.

Hi I check your sketch and seems quite ok.

But I think you must add AUX pin or put a pull up resistor on It, with no AUX not work for me, but with aux I have a correct send.

And Arduino Json have some problem on serialize on String

Hi taurushappy,
you can use ArduinoJSON library, (I’m going to publish a post on how to use It).

You can

  DynamicJsonDocument doc(512);

  // Set the values in the document
  doc["energyLifetime"] = 21698620;
  doc["energyYearly"] = 1363005;

String buf;
serializeJson(doc, buf);

ResponseStatus rs = e32ttl.sendMessage(buf);

Remember you have a size limit on message size of the lora E32.

The code is untested, but I think It can be usefully to understand.

Tell me if It’s ok.

Hi Michiel

now It’s possible to check the status with

if (pcf8574.begin()){
Serial.println("pcf8574 started!");
}else{
Serial.println("pcf8574 not started!");
}

if (pcf8574.digitalWrite(P7, startVal)){
Serial.println("Write ok");
}else{
Serial.println("Write not ok");
}

It’s also possible to get last writeStatus with

uint8_t getTransmissionStatusCode() const {
return transmissionStatus;
}

bool isLastTransmissionSuccess(){
return transmissionStatus==0;
}

Bye Renzo
