@martinayotte : Actually, I don't know. How can I find this information?
If on your PC, the DNS is the same 192.168.0.254, then try to ping "pool.ntp.org" from the PC.
If it is not working there too, then your router is misconfigured.
As I said, try using 8.8.8.8 as DNS, it should work ...

Code: Select all

IPAddress dns(192, 168, 0, 254);     //DNS
Is this DNS really able to resolve it ?
Is this address of your router ?
Doesn't have external DNS enabled ?
Did you tried using 8.8.8.8 as the DNS ?

Is there a way to know the IP address of a client connected to the ESP32 as SoftAP using Arduino IDE ?
client.remoteIP();

After switching the LDO the power consumption dropped to around 0.14mA.
Which kind of new LDO have you chosen ?

Could you or someone suggest such chip/IC ?
There are boards on the market that use MAX3421 as USB HOST adaptor.

Googling a bit will reveal tons of tutorial, some using libraries, some plain code, like this one :

Possible solutions of were can i get the library??
Since 4x4 matrix need simple 4 GPIOs as outputs and 4 other GPIOs as input, there is no need for complex library.

Re: Can ESP32 handle two sprinf() strings at the same time?

char Fecha[10];
char Hora[5];
The problem is probably related to the fact that your strings are to small to have their respective NULL ending characters, so memory get corrupted ...
Make them bigger than the length you expect, like :

Code: Select all

char Fecha[16];
char Hora[8];
