Hi Gilles,
can you send me the code you use and the library version.

Hi Morne,
First, try the example to send the email that you can find to the examples folder and give me the test response.
It seems correct, so there may be a network problem, but we’ll have the response with the standard test.

Hi ps2chiper,
I push the branch, you can find It here.

I create a define for EthernetLarge

	#define DEFAULT_EMAIL_NETWORK_TYPE_SAMD 	NETWORK_ETHERNET_LARGE

And you also must uncomment

#define SSLCLIENT_WRAPPER

but in the branch is already uncommented.

You must add thrust anchors with this command

    emailSend.setTrustAnchors(TAs, (size_t)TAs_NUM, A3);

I don’t test It, but with your change on bearssl_ssl.h header.

/** \brief Optimal input buffer size. */
//#define BR_SSL_BUFSIZE_INPUT (16384 + 325)
#define BR_SSL_BUFSIZE_INPUT (1024 + 325)

/** \brief Optimal output buffer size. */
//#define BR_SSL_BUFSIZE_OUTPUT (16384 + 85)
#define BR_SSL_BUFSIZE_OUTPUT (1024 + 85)

I also change SSLclient.h from this
unsigned char m_iobuf[2048];
To this
unsigned char m_iobuf[BR_SSL_BUFSIZE_BIDI];
as advised on your example.

But I don’t understand how to manage TLS encryption.

Hi ps2chiper,
I’m going to create a branch of my library with a basic implementation.
When finished, I’m thrilled to help me complete the work.
I will write here when the version is created.

Hi all,
Can it be a solution to use a device (like esp32-s2) with USB OTG and connect It directly to the USB like Octoprint???

Hi Theo,
It seems all ok, try to make any change
WOR role
and
Tran Mode
of DTU, in a previous version of the E22 client, Ebyte made some parameters errors.

If you have another E22, try to send a message to check if you have some receiving problem.

Hi Arkadiusz,
I don’t check the firmware, and I don’t know well the board, if you check that I think there wasn’t a way.
But I don’t know if the protocol was the same of standard communication via serial usb.

We must check that possibility and we can go to use that to connect.

Bye Renzo

[Renzo Mischianti]

Ahh! Yes ok I didn’t remember that.

To set correct power you must add the define, you can refer to this paragraph.

But I think that the problem isn’t that.

For debug uncomment the define in LoRa_E22.h file, but I think also this can’t add more information.

Try to change/remove resistor and connect to 5v.

Hi olo,
I don’t know that board and to work a wifi module need more pins check
MKS WIFI for Makerbase Robin: boards and how to wiring esp12 & NodeMCU – 1

I think it’s possible but now I don’t check that.

MKS WIFI need an esp8266.

Hi Theo,
I don’t know if e22 and e90 are compatible.

You must declare the correct power, but it isn’t that the problem
The 30 need more ampere and it’s better if you use 5v
I test the module in Vero close position without problem

Hi,
if you uncomment the debug variable you can get additional info
But I think in your case there is a wiring problem
Try to remove/change the resistor.
What is the exact model you use?

[Renzo Mischianti]

Very interesting,
probably I’m going to test SSLClient to implement TLS for WiFi also.
Keep in touch Renzo

Hi Theodoros,
It seems all ok; try to put it all on a breadboard and activate the debug.
Which error do you receive?
Bye Renzo

[Renzo Mischianti]

Hi ps2,
fantastic, can you share your coffee to integrate on the library..
Bye Renzo

[Renzo Mischianti]

Hi,
here an example

EMailSender::FileDescriptior fileDescriptor[2];
fileDescriptor[1].filename = F("test.txt");
fileDescriptor[1].url = F("/test.txt");
fileDescriptor[1].storageType = EMailSender::EMAIL_STORAGE_TYPE_SD;
 
fileDescriptor[0].filename = F("logo.jpg");
fileDescriptor[0].url = F("/logo.jpg");
fileDescriptor[0].mime = "image/jpg";
fileDescriptor[0].encode64 = true;
fileDescriptor[0].storageType = EMailSender::EMAIL_STORAGE_TYPE_SD;
 
EMailSender::Attachments attachs = {2, fileDescriptor};
 
EMailSender::Response resp = emailSend.send("<receipe@gmail.com>", message, attachs);

Bye Renzo
