Hi nicoxx,
your reply went to spam, I restored It.

I have added a new version that tries to fix this problem, if you can give me feedback.

Hi nicoxx,
from the log you send me

/**************************/

It seems that the IP you passed to the server was wrong, and It set 0.0.0.0.

Hi,
I ask to the people that use e32 for a production project.
They say that to raise best performance more than 8km that is the limit of e32) they use a 12dbi antenna positioned ad 4 meter high to the receiver and 8dbi antenna to the sender at 1 or 2 meter height.
They have 868mhz device, and if the use 915mhz antenna the distance is reduced by half (problem start from 4km).

So I think you must consider:
– good voltage and amperage;
– correct antenna (mhz and dbi);
– put the antenna very high;

Keep in touch for the result of your test.

Hi rb3rg,
It’s important to use the correct antenna (for the relative frequency) and to power the device with a stable 5v with good amperage.
I ask to another use that use the devices in a agriculture product how he manage the device to get the maximum distance.

Hi Bert,
the library you use does not support pcf8574, so I think It’s better if you create a simple function to scan which pin is selected and retrieve the keypad button.

Ciao Dario,
sull’ide puoi usare direttamente D5 al posto del numero, e ci pensa lui poi a fare la conversione.

Ciao Dario,
gli esp uno vale l’altro (a meno di dover gestire il risparmio energetico), è bene prendere quello che ci soddisfa di più.

Per i pin basta che controlli sulla scheda sono tutti numerati ad eccezione del joistick che sembri usare questi pin FLATH, RSET, D5, D6, e D7, ma non è chiaro a cosa corrisponde FLATH.
E del display oled che usa SDA e SCL connessi a D1 e D2 rispettivamente.

I pin che trovi sulla scheda a parità di nome hanno le stesse funzioni di un qualsiasi esp8266.

Ciao Renzo

Hi moonman,
No sorry nothing of that.

Hehehe.. good!
If you want, send us some photos of your work.

Hi moonman,
you can’t send more than 58byte in a single call, but if you use a structure with some packet instruction, you can manage It via software.

struct Packet {
	byte deviceId;
	byte msgId;
        byte[54] rawBinary;
        bool end;
};

with a similar structure, you can identify a sender device and the msgId, and you can rebuild the complete message in the server and use end == true to know if the stream was complete.

Hi Rainer,
try to format the SD of the printer.

Hi,
You can find it here

Hi tarpacik,
I think It’s better if you use an example with the library.
Bye Renzo

[Renzo Mischianti]

Hi tarpacik,
you send/receive more than 1000 messages per second, and you can’t do that.
