Configuration for transparent transmission

[Flowmikos]

Hello there (I’m new on the forum), I’m having a bad time with the Lora Module right there…
I desperately tries to configure them but nothing works.

Here is the configuration code :

/*
 * LoRa E32-TTL-100
 * Set configuration.
 * http://mischianti.org/2019/10/29/lora-e32-device-for-arduino-esp32-or-esp8266-configuration-part-3/
 *
 * E32-TTL-100----- Arduino UNO
 * M0 ----- 3.3v
 * M1 ----- 3.3v
 * TX ----- PIN 2 (PullUP)
 * RX ----- PIN 3 (PullUP & Voltage divider)
 * AUX ----- Not connected
 * VCC ----- 3.3v/5v
 * GND ----- GND
 *

void setup() {
	Serial.begin(9600);

Here is the sender code :

#include "Arduino.h"
#include "LoRa_E32.h"

#define LoRa_E32_DEBUG

LoRa_E32 e32ttl(2, 3);

void setup() {
// put your setup code here, to run once:
	Serial.begin(19200);
	e32ttl.begin();
}

void loop() {
// put your main code here, to run repeatedly:
	char frame[59] = "test\n";
	ResponseStatus rs = e32ttl.sendMessage(frame);
	Serial.println(frame);
	Serial.println(rs.getResponseDescription());

}

Here is the receiver code:

#include "Arduino.h"
#include "LoRa_E32.h"

#define LoRa_E32_DEBUG

LoRa_E32 e32ttl(2, 3);

void setup() {
// put your setup code here, to run once:
	e32ttl.begin();
	Serial.begin(19200);
}

void loop() {
// put your main code here, to run repeatedly:
	Serial.println(millis());
	ResponseContainer rs = e32ttl.receiveMessageUntil('\n');
	Serial.println(rs.data);
	Serial.println(rs.status.getResponseDescription());
}

If the sender is active the receiver stop without displaying the message:<

If the sender is inactive it continues without stopping:

I don’t understand…

Hi Flowmikos,
Try to put a value on ADDL or ADDH, then you must set a delay, the device can’t send message at 8Mhz (8000 msg per secs).
Retry and tell me the result.

Hi Renzo,

I put a delay(60); and I set the ADDL value to 0x01 with the sender and the receiver !

Here is the sender code :

#include "Arduino.h"
#include "LoRa_E32.h"

#define LoRa_E32_DEBUG

LoRa_E32 e32ttl(2, 3);

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
e32ttl.begin();
}

void loop() {
// put your main code here, to run repeatedly:
delay(60);
char frame[59]="test\n";
ResponseStatus rs = e32ttl.sendMessage(frame);
Serial.println(frame);
Serial.println(rs.getResponseDescription());

}

The reveicer code :

#include "Arduino.h"
#include "LoRa_E32.h"

#define LoRa_E32_DEBUG

LoRa_E32 e32ttl(2, 3);

void setup() {
// put your setup code here, to run once:
e32ttl.begin();
Serial.begin(9600);
}

void loop() {
// put your main code here, to run repeatedly:
Serial.println(millis());
ResponseContainer rs = e32ttl.receiveMessageUntil('\n');
Serial.println(rs.data);
Serial.println(rs.status.getResponseDescription());
}

The same result is shown, if the sender si activated the receiver will just stop…

Hi Flowmikos,
I don’t know if the problem was only that but 60millis can be managed by this devices, try a test with 3000 millis or more.
If you don’t receive response, try to enable DEBUG and send the result.

Bye Renzo

[Flowmikos]

I tested it down to 45 ms without problem (before this configuration problem),

I found that the problem is that the Lora Module lose the configuration when the module is powered down, do you know how to configure it so that it keep it’s configuration ?

ResponseStatus rs = e32ttl100.setConfiguration(configuration, WRITE_CFG_PWR_DWN_LOSE);

Something to change here ?

[Renzo Mischianti]

Damn, It’s surely that, I had not noticed the parameter.

	ResponseStatus rs = e32ttl.setConfiguration(configuration, WRITE_CFG_PWR_DWN_SAVE);

For the speed, you had try to bid distance at 45ms if some package comes after others.

But you

[Flowmikos]

But I ? bit distance ?

Also I have to switch to the “ioDriveMode” : “IO_D_MODE_OPEN_COLLECTOR”.

I followed your diagrams It is normal ? (the driagram confuse me because the PIN 3 and 2 is inverted for the arduino but I followed this configuration :

* E32-TTL-100—– Arduino UNO
* M0 —– 3.3v
* M1 —– 3.3v
* TX —– PIN 2 (PullUP)
* RX —– PIN 3 (PullUP & Voltage divider)
* AUX —– Not connected
* VCC —– 3.3v/5v
* GND —– GND

).
Thanks for the replies.

Hi Flowmikos,
thanks for reporting, I will immediately fix the scheme, could you tell me the exact article.
Thanks again Renzo
