Good morning, we are not Arduino experts and we do not speak English.
The rover, after assembly, gave disconnection problems with both smartphones used for testing (Samsung, S22 Ultra and A52s 5G). Reading the FAQ on the manufacturer’s website (SunFounder) we found 2 solutions to the problem:
-
replace the integrated antenna with an external one (done);
after this change the rover worked perfectly -
update the ESP32-CAM FIRMWARE from version 1.4.0 (factory) with 1.4.1 downloaded from the SunFounder website, to be able to change the Wi-Fi transmission channel (from 1 to 11) and avoid conflicts with other devices: we also performed this update to improve the connection.
Problem: after successfully installing the 1.4.1 firmware on the ESP, the rover no longer connects to both smartphones reporting “incorrect PW”.
Through the forum we understood that it is possible to replace the connection method (from direct to the phone to the one via home network) by opening the rover’s .ino program through the Arduino IDE, adding 2 libraries (softPWM and SunFounder AI CAMERA) and modifying some parameters of the #define within the program (SSID and PW of our home network), then reload it on the R3, but we have not solved the problem.
How can we solve it? Do you have any advice?
Thanks.
