E32-868T20D configuration problem #18

Closed masc-it closed 3 years ago

masc-it commented 4 years ago

I have a sender (Arduino Mega) and a Receiver (esp32, heltec v2).

These are the params:

MEGA

----------------------------------------
Model no.: 45
Version  : D
Features : 14

Mode (HEX/DEC/BIN): 0/0/0
AddH (HEX/DEC/BIN): 0/0/0

OptionPower (HEX/DEC/BIN)       : 3/3/11
----------------------------------------

Everything seems the same on both the modules, but the receiver doesn't receive anything at all.

Receiver loop code

if (ESerial.available()) {

    Transceiver.GetStruct(&MyData, sizeof(MyData));

    Serial.print("Count: "); Serial.println(MyData.c);

  }

Sender loop code

  strcpy(MyData.c , "test");

  Transceiver.SendStruct(&MyData, sizeof(MyData));

  Serial.print("Sending: "); Serial.println(MyData.c);
  delay(500);

The structure sent:

struct DATA {

  char c[10];

};

Parameters:

Transceiver.Reset();
  Transceiver.SetMode(MODE_NORMAL);
  Transceiver.SetChannel(6);
  Transceiver.SetAirDataRate(ADR_2400);
  Transceiver.SetTransmitPower(0b11);
  Transceiver.SetFECMode(OPT_FECENABLE);
  Transceiver.SetUARTBaudRate(UDR_9600);
  Transceiver.SetPullupMode(OPT_IOPUSHPULL);

@KrisKasprzak any ideas?

I've had issues in sending structs between 2 different MCU's as well. I believe it's due to how each compiler packs the data--odd it can't match a simple char.  Some claim you can only use uint16_t between different boards. Try using EasyTransfer.h (that lib has a .h for hardware serial and software serial application). I'm having to use that lib on a current project and it works. I send / receive data using EasyTransfer and the EBYTE lib for module management. madsci1016/Arduino-EasyTransfer

@KrisKasprzak can you provide some samples using EasyTransfer? I think it would be useful for lots of people :)

vindolin commented 3 years ago

EDIT Turned out that the I had to change the M0 pin on one of my boards and now I can finally transmit data :)

@onipot I have the same problem with two ESP32 MCUs.

Transceiver.PrintParameters() prints the default values on both modules.

----------------------------------------

Have you tried just sending/receiving single bytes instead of the struct, just to see, if the transmission works?

I first tried Transceiver.SendStruct(), then the EasyTransfer library and finally just Transceiver.SendByte(58) in the TX loop, and on the RX side:

if (Serial2.available()) {
    Serial.println(Transceiver.GetByte());
}

But all to no avail :(

I'm ordering some new modules now to see if one is broken.

I have tested sending recieving struct and bytes. I'll have another look
