Hi 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
#endif

and the network you must use is this

#define NETWORK_MBED_WIFI	(14)	// Arduino GIGA R1 WiFi

Put in substitution of the original SD.begin declaration.

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,
Renzo

Hi 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.

Hi Pashazaur,
The libraries support only the specified devices that are built for.
E32, E220 and E22.

Hi,
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

Hi monaco,
modify #define DEFAULT_STORAGE_TYPE_ESP32 STORAGE_LITTLEFS
directly in SimpleFTPServerKey.h it can’t manage from the external.

Hi Monaco,
I tried It, and it seems to work. Can you explain the step you did?
Bye Renzo

[Renzo Mischianti]

In your code, you send and put on sleep immediately. I think you must add a delay time to allow flushing the buffer.

Ahh! Okay, you don’t use the library.
If you want to connect the device directly, it’s simple for simple things but becomes complex when you must manage timing and structure. I advise you to use the library.

Hi F1SSF,
the module does not return to normal mode; you must put It in normal mode by connecting the Lora dev pins to the microcontroller; the library takes control and changes the values by using the output of the pins.
Check your connection, and try some simple test like getconfig setconfig and check the result.
Remember to connect all pins to do the tests.

Hi Furkanb,
It seems that the data received from the device isn’t correct, and the library can’t convert.
This happened probably because the data was corrupted; try to check the power supply and the wiring noise.

HI,
I understand that this case is replicated with a standard Linux FTP client. I’ll fix it soon.
