Hi Pashazaur,
Yes, the power supply is very important for raising a good distance, and the antenna is also very important.
Bye RenzoHi Gilles,
As you write, it’s very difficult to find a provider without SSL or TSL. If I have some additional information, I will write here.
Bye RenzoHi,
I think this can be helpfull, I use GMail but I found this doc.

Give us some feedback. Bye, Renzo
Hi pashazaur,
you can follow the steps for E32 that you can find here.Bye Renzo
Hi Zemmo,
There can be various problems, but I think a good way to do that is to change the library to use the native stack of ESP32, and you can prevent any issues with authentication.
You can find more info here.Could you give us feedback about the result and if the problem continues we are going to look into the problem in depth.
Bye Renzo
Hi Boby,
Yes, you are right, I implemented the Arduino GIGA R1 WiFi only on EmailSender, so for now it isn’t supported by that, sorry.
I try to update the library in the future.
Bye RenzoHi boby,
the configuration is wrong, the correct section you must modify is this// Arduino MBED microcontrollers configuration LIKE Arduino GIGA #ifndef DEFAULT_EMAIL_NETWORK_TYPE_ARDUINO_MBED #define DEFAULT_EMAIL_NETWORK_TYPE_MBED NETWORK_MBED_WIFI #define DEFAULT_INTERNAL_ARDUINO_MBED_STORAGE STORAGE_NONE #define DEFAULT_EXTERNAL_ARDUINO_MBED_STORAGE STORAGE_SD #endifand the network you must use is this
#define NETWORK_MBED_WIFI (14) // Arduino GIGA R1 WiFiBye Renzo
Hi,
you can find an example here.Check also the documentation here.

Hi Gadzilla,
Just to clarify: the library doesn’t add any extra bytes—the E22 module sends the wake‑up preamble on its own. If you notice missing characters, it usually means the MCU hasn’t woken up quickly enough to catch the start of the UART stream.
Please try lengthening the WOR period so the receiver stays awake a bit longer, and let me know if that solves the problem.
Best,
RenzoHi Pataone,
This can be generated by noise on the channel. I have already heard of problems like that. When I have some time, I will fix it via code and release a flag to bypass that problem.

Bye RenzoHi Pashazaur,
The libraries support only the specified devices that are built for.
E32, E220 and E22.
Bye RenzoHi,
it’s correct, you need a logic level converter or simply a voltage divider from tx of Arduino and rx of esp32.Here a simple connection with a voltage divider
