EByte E32 868T30D reboot loop

[Claudio Barca]

Ciao Renzo,

for a particular use case, I need to add an EBYTE 868T30D as LoRa receiver to TTGO T-CALL SIM800L board.

I use PlatformIO with your library

#include <Arduino.h>

#include <HardwareSerial.h>

#define E32_TTL_1W
#define FREQUENCY_868

#include "LoRa_E32.h"

#define LoRa_E32_DEBUG
#define DEBUG_PRINTER Serial

#define Receiver Serial2

uint32_t serialConfig = SERIAL_8N1;

#define rxE32pin 27
#define txE32pin 19
#define M0 33
#define M1 35
#define AUX 34

void printParameters(struct Configuration configuration);

void printModuleInformation(struct ModuleInformation moduleInformation);

void setup()
{
	Serial.begin(115200);
	delay(500);

	Receiver.begin(9600, SERIAL_8N1, rxE32pin, txE32pin);
	delay(500);

	LoRa_E32 e32ttl100(&Receiver, AUX, M0, M1);

	// Startup all pins and UART
	e32ttl100.begin();

	ResponseStructContainer c;
	c = e32ttl100.getConfiguration();
	// It's important get configuration pointer before all other operation
	Configuration configuration = *(Configuration *)c.data;
	Serial.println(c.status.getResponseDescription());
	Serial.println(c.status.code);

	printParameters(configuration);

	ResponseStructContainer cMi;
	cMi = e32ttl100.getModuleInformation();
	// It's important get information pointer before all other operation
	ModuleInformation mi = *(ModuleInformation *)cMi.data;

	Serial.println(cMi.status.getResponseDescription());
	Serial.println(cMi.status.code);

	printModuleInformation(mi);

	c.close();
	cMi.close();
}

void loop()
{
}

void printParameters(struct Configuration configuration)
{
	Serial.println("----------------------------------------");

	Serial.print(F("HEAD BIN: "));
	Serial.print(configuration.HEAD, BIN);

	Serial.print(F("SpeedUARTDataRate BIN : "));
	Serial.print(configuration.SPED.uartBaudRate, BIN);
	Serial.print(" -> ");
	Serial.println(configuration.SPED.getUARTBaudRate());
	Serial.print(F("SpeedAirDataRate BIN  : "));
	Serial.print(configuration.SPED.airDataRate, BIN);
	Serial.print(" -> ");
	Serial.println(configuration.SPED.getAirDataRate());

	Serial.print(F("OptionTrans BIN       : "));
	Serial.print(configuration.OPTION.fixedTransmission, BIN);

	Serial.print(configuration.OPTION.wirelessWakeupTime, BIN);
	Serial.print(" -> ");
	Serial.println(configuration.OPTION.getWirelessWakeUPTimeDescription());
	Serial.print(F("OptionFEC BIN         : "));
	Serial.print(configuration.OPTION.fec, BIN);
	Serial.print(" -> ");
	Serial.println(configuration.OPTION.getFECDescription());
	Serial.print(F("OptionPower BIN       : "));
	Serial.print(configuration.OPTION.transmissionPower, BIN);
	Serial.print(" -> ");
	Serial.println(configuration.OPTION.getTransmissionPowerDescription());

	Serial.println("----------------------------------------");
}

void printModuleInformation(struct ModuleInformation moduleInformation)
{
	Serial.println("----------------------------------------");
	Serial.print(F("HEAD BIN: "));
	Serial.print(moduleInformation.HEAD, BIN);

Hi Claudio,
the configuration is wrong, you don’t initialize the Serial, the library do it for you.
You can look at this topic with the same esp32 configuration problem.

EByte LoRa e32 not working on esp32: sends a random number, the other reads

If you need more information ask without problem.

Good afternoon Renzo.
I have the same reboot-loop problem. I am using your example program to read the E32 configuration. It worked until yesterday. But when I used your “E32_Transparent_transmission” program, it didn’t work. And I reinstalled the read config one, but it no longer works. Is it possible that the E32 is damaged?

[Renzo Mischianti]

Hi,
the usage of Serial2 can’t work, because you do the begin and inside the library I do begin again.
To use custom pin on esp32 you can refer this article

Ebyte LoRa E32 device for Arduino, esp32 or esp8266: library – Part 2

You can’t do

    LoRa_E32 e32ttl100(&Serial2, AUX_PIN, M0_PIN, M1_PIN);
    Serial2.begin(9600, SERIAL_8N1, RX2_PIN, TX2_PIN);
    e32ttl100.begin();

because you start the serial 2 times
you must use something like this

LoRa_E32(RX2_PIN, TX2_PIN, &Serial2, AUX_PIN, M0_PIN, M1_PIN);

ood afternoon Renzo, when placing the recommended instruction and compiling the program it throws me an error

Hi Hector,
check Claudio configurazione, you must add the object Mame.

Sometime reboot loop can be generated by

• wrong wiring
• wrong usage
• and the e32 that have some waste on flash, to fix this problem you need the usb-ttl EByte device with the original software

I have verified and reset factory config to my E32868T30D.
It work as Transmitter on TTGO TCALL SIM800L.

I’cant run it as Receiver. Continuous loop rebooting.

This is my PIN config.

This is my Setup and Loop (empty).

This is the result of printConfig :

Starting Receiver E32Series
No response from device! (Check wiring)

SpeedParityBit BIN : 10 -> 8E1
SpeedUARTDataRate BIN : 101 -> 38400bps
SpeedAirDataRate BIN : 0 -> 0.3kbps
OptionTrans BIN : 1 -> Fixed transmission (first three bytes can be used as high/low address and channel)
OptionPullup BIN : 0 -> TXD, RXD, AUX are open-collectors
OptionWakeup BIN : 10 -> 750ms
OptionFEC BIN : 0 -> Turn off Forward Error Correction Switch
OptionPower BIN : 1 -> 17dBm

Any help is appreciated.
thank’s

I have changed board, using now a NodeMCU ESP8266 as Receiver.
The Transmitter is running on TTGO TCALL, but I cannot receive any on NodeMCU.
As you can see below, ALL settings parameters are the same between TX and RX.

There are the TTGO TCALL pin’s (TRANSMITTER)

// ——————————————–
//    PIN TCALL <–> E32868T30D

#define PIN_M0 19  // connect this to the EBYTE M0 pin  | GIALLO |  ARANCIO

#define PIN_TX 12  // connect this to the EBYTE RX pin  | BLU    |  BLU
#define PIN_RX 14  // connect this to the EBYTE TX pin  | VIOLA  |  VERDE
#define PIN_AUX 34 // connect this to the EBYTE AUX pin | GRIGIO |  VIOLA
LoRa_E32 e32Series(PIN_RX, PIN_TX, &ESerial, PIN_AUX, UART_BPS_RATE_9600, SERIAL_8N1);

This is the output of printParameters of TRANSMITTER.

The loop receiver code is that:

if (e32Series.available() > 0)
{
Serial.println(“———-“);
ResponseContainer rc = e32Series.receiveMessage();
Serial.println(rc.data);
// Is something goes wrong print error
if (rc.status.code != 1)
{
rc.status.getResponseDescription();
}
else
{
blinkled(1);
// Print the data received
Serial.println(rc.data);
}
}

Any signal was received from e32Series serial port, ii is not available.

Any suggest please ?

Thank’s

Hi Claudio,
check with tester of m0 and M1 are correctly setted.
Bye Renzo

[Claudio]

M0 & M1 must be grounded for transparent mode ?

[Renzo Mischianti]

Yes, all LOW.
