Hi Gilles,
I think that ° isn’t a character UTF-8, but I set UTF-8 encoding.

Hi ARNAB,
you have set
#define DEFAULT_EMAIL_NETWORK_TYPE_ESP8266 NETWORK_ESP8266_242

but you use 2.7.4 esp8266 core.

Hi Davidd,
follow the topic there is write that you must certificate the sender and you must change the define inside the file EMailSenderKey.h.

Hi Davidd,
you can refer this topic, and SendGrid have an exaustive documentation.

Hi Davidd,
if you use Ethernet Shield please refer to the article

Send email with attachments (v2.x library): Arduino Ethernet – 1

there are some limitation on secure connection and in Memory size like you can see on this topic

Hi Ayush,
I write an article on broadcast, I think you can find the solution on this article

Hi Fernando,
you must reduce the DigitalInput object to a byte like so:

byte byteValReadAll = 0;

void setVal(uint8_t pin, uint8_t value){
	if (value==HIGH){
		byteValReadAll = byteValReadAll | bit(pin);
	}else{
		byteValReadAll = byteValReadAll & ~bit(pin);
	}

}

[...]
	setVal(P0, digitalInput.p0);
	setVal(P1, digitalInput.p1);
	setVal(P2, digitalInput.p2);
	setVal(P3, digitalInput.p3);
	setVal(P4, digitalInput.p4);
	setVal(P5, digitalInput.p5);
	setVal(P6, digitalInput.p6);
	setVal(P7, digitalInput.p7);
	
	Serial.println(byteValReadAll, BIN);
[...]

Yes, all LOW.

Hi Orvasson,
The flash memory use a SPI protocol, if I remember exist a specified library to simplify the usage without limitation.

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

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

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);

Hi Josh,
check the logic level of M0 and M1 if raise correctly, with 5v power sometime It’s hard to change.
Check if are high.
If you have a FDTI use software serial to debug or to control the e32, debug information It’s important to discover the problem.

Bye Renzo

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.
