Yes, it’s correctly, you can refer the article
Ebyte LoRa E22 device for Arduino, esp32 or esp8266: library – 2

Hi George,
For E32, I develop a gateway with a graphical user interface that uses WebSocket (not MQTT).

EByte LoRa E32 gateway: manage via REST and WebSocket (esp8266, esp32) – 1
EByte LoRa E32 Web Manager: description, configure and demo (esp8266, esp32) – 2

You can add MQTT with a few codes, and if you have some patience, I will develop It for E22 and E220, but now I must finish the E220 library and documentation.

If you have some time to spend, we can collaborate for the E220 gateway, the conversion of the E32 version Is pretty fast, but the web interface to control it needs more time.

I think that spending more than 10$ on a gateway It’s a stupid thing :P.

Hi George,
I think you can use 915, but you can refer to the global table that I shared here

Hi George,
we can schematize like so:

                       E32                       E22                       E220
Chip                   sx1276-sx1278             sx1262-sx1268             LLCC68
Range                  3Km - 8Km                 5km - 11km                5Km - 10Km
Repeater               No repeater               Repeater                  No repeater
Remote conf            No                        Yes                       No

Power consumption      Best                      Good                      Very Good
                       Sleep 4μA                 Sleep 496μA               Sleep 6μA
Transmission and receiving have similar power consumption.

Message size bytes     58                        240                       200
Buffer size bytes      512 (ok)                  1000 (good)               400 (why?????)

Max air data rate (bps) 19.2k                    62.5k                     62.5k

Encryption             One standard              Configurable              Configurable crypt
Price                  Less expensive            More expensive            Less expensive

I think all devices are valid, but we must pay attention to buffer size, security and prices.

I think the E220 is a candidate for the best device, but 400b of the buffer can be dangerous if you want to use the max packet size and receive three messages simultaneously, you can lose one of them.

The E32, if you can find It at the best price, has a good compromise of all characteristics. But if you have sensing information, you can’t choose it; another pirate E32 can read your information (It must know frequencies, etc., not so simple).

If you have a reasonable budget, the E22 has the best characteristics, but sensing on power consumption (even if It’s low) from 4μA to 496μA can be a big step.

Hi Melis,
It’s not so simple to do that.
LoRa uses a small packet, and the speed can’t be elevated so that you can try, but the result isn’t sure.

Hi scoosys,
ahh!! the SSL for Arduino Mega Ethernet was disable by default.

It’s something else needed by the server. You must check documentation of the server.
Bye Renzo

[Renzo Mischianti]

Hi scoo,
sorry I lost the part of your topic where you write that you use

Im using an MEGA with ENC28J60 Shield.

the Arduino Ethernet not support SSL so you can’t use normal provider. You must use provider like sendgrid.
For more information about Ethernt and Arduino read the article

Hi ps2chiper,
I think It’s a good idea.

If you want, I’d be pleased if you wrote an article with all the steps, and I can help you with the schemas, cover, and others. Your knowledge about the problem can be helpful for other people.

Bye Renzo

Hi scoosys,
I found this answer to your problem

To fix this you need to add the full domain name or a workgroup name to the network identification.

Open the System Properties and go to the Computer Name tab (Network Identification on Win2000 server). You will see “MACHINE-name.” in the full computer name field. You will need to append your full domain name or workgroup name here. Click the “Change” button (Properties for Win2k) on the Computer Name tab, then click “More”. Enter the full domain name or workgroup name in the “Primary DNS suffix of this computer” and click OK. After you OK the change, you will be required to reboot.

When you come back up, the Network ID page should show the Full machine.domain.com name.

Other causes may be, a failure to assign a valid email address to the mandatory From property:
Mail.From = “name@domain.com”
This error may also occur if a name instead of an email address is specified for this property. Another reason is, invalid syntax in an email address passed to any of the methods: AddAddress, AddCC, AddBcc or AddReplyTo.

I think the second part can help you.

I don’t need if necessary for your provider (but I think no) you can set the value to HELO message with emailSend.setPublicIpDescriptor(<Value of HELO>)

If you don’t need authentication you must set It with this command

emailSend.setUseAuth(false);

Hehehehehhe… fantastic!
Would you like to write the article where explain how you find this solution? and how to use the library with bluepill?

I think It’s more correct that you write that and take the paternity 😛

Hi,
I found these informations

The error message “Relaying disallowed” will occur in the following cases.
From address that you are trying to add in SMTP client might not be listed in your Send Mail as section (in Zoho Mail). Please ensure that the email address that you are trying to use is one of the From addresses present in your Send Mail as section. Refer help to locate Send Mail as page.
If “Outgoing Server Requires Authentication” option is not enabled in the SMTP client. Ensure that the settings entered are correct by referring this link help page.

what is the port you use for SMTP server?

Can you try with gmail (with application password or insecure app)?

Bye Renzo

[Renzo Mischianti]

Thanks, Paul,
I think many people had written to It, after only a couple of weeks they contacted me.
If you need a preview of the library, contact me, I must write and test all the examples, and I have already written the first two articles about that.
Thanks again Renzo

[Renzo Mischianti]

Sorry, Arkadiusz,
I lost your reply, but in brief, do you have in mind to standardize the protocol of BeePrint?
And how do you intend to connect to the 3D printer?
All suggestion is appreciated; if you have a route to follow, we can think about that.

Hi Alejandro,
I think the problem is the debounce time and setting; if an input pin goes up then goes down in the interval, you lost the change.
Try to set

#define READ_ELAPSED_TIME 10

To 0 so you remove debounce, and you must use interrupt.

You can refer to the pcf8574 example.

Hi Sezgin,
No, E32 doesn’t have RSSI; you must select E22 or E220 (library available soon).
