Hi FC3,
you can use TinyGSM library.
Pratically you must connect your device (there is a long list of supported device) and It offer a series of method to do HTTP request or MQTT request.
Bye RenzoHi Erjon,
try to follow the steps for Arduino UNO (if you use It); then there are a lot of topics about how to configure the send grid to send email.Send emails with attachments (v2.x library): Arduino Ethernet – 1

Hi William,
Sorry, I lost the first message on this topic.
But I don’t have any measurements for esp32 and E220, but as described here
ESP32 practical power saving: deep sleep and hibernation – 3
remember that there are several differences between the different prototype boards.
Bye RenzoHi Sid,
try to put the procedure in a function to check if something in the context remains dirty.
Use only local variables and not global ones.
Bye RenzoHi William,
It’s normal the device use a WOR cycle to check if some message is coming, you can find more information here.WOR Cycle
A critical configuration parameter is WOR Cycle, for the sender is essential because It adds a long preamble to the message (long as wake time). The handset uses the wake-up time as the cadence for checking a wake-up message. So if the receiver checks every 2000ms (polling time) if there is a message, the sender adds a 2000ms preamble. The receiver intercepts the message preamble, waits for the actual message to read, and returns to power save mode.So If you want to maximize the power save, you must put minimal WOR Cycle. If you want more efficiency, you must do the inverse.

No,
for GIGA exists specified API with custom operators.
Here is my implementation, but it does not work for now.
Bye RenzoHi Syrinx,
Sending mail with GIGA works correctly, but I think USB stick support can’t be added because of some problems with the library’s scope.
I release the official new version of EMailSender soon.
Bye RenzoHi William,
first of all, try to send a String and check if It’s transferred correctly.
Then, try to use a char or byte to set the value.
Bye RenzoDon’t worry, William, I must write the same articles for E32 for E220, but for now, the examples can be useful.
Rye RenzoHi William,
The E220 has a different setting structure; please take a look at the examples of the library.
Here, you can find the WOR sender and WOR receiver configuration.Here is the sketch to send WOR, and here is the sketch to receive It.
Bye Renzo
