Thank you again.
To download the KCS firmware, I am following the procedures described previously in this thread by JarekD, say (sorry for repeating):
Brand new board, first power up:
1) Downloads:
USB driver first: https://www.kincony.com/download/CH341SER.zip
Firmware flash tool: https://www.kincony.com/wp-content/uploa..._3.9.2.zip
Latest firmware: https://www.kincony.com/forum/showthread.php?tid=3791 (I tried either this bin file, the KCS_KC868_A16_V2.2.2.bin, and the KCS_KC868_A16_V2.2.20.bin, which seems to be newer)
2) Install USB serial driver
3) Prepare board: if you have a radio transmitter and receiver, remove it
Connect USB cable
Connect 12V power
4) Flash the firmware according to instructions:
https://www.kincony.com/esp32-kcsv2-firmware.html (see the print of thdowloadtoo software after flashing)
5) Power down, power up the board. Clicking the reset button is NOT enough.
For JarekD, after these steps, the AP finally appeared on the list of WiFi networks, and he was able to connect to http://192.168.4.1. Unfortunately, in my case, the AP does not appear on the list of WiFi AP networks. Instead, the board´s power LED keeps dimming, now every ~1 second. The onboard 3.3 V fluctuates correspondingly. See attached photo. I repeated the tests today, with the (+) red wires attached to the output´s connectors: no success.
Regarding the power supply, I couldn´t provide a >1.5 A yet, sorry. I will try it again with a 12 V - 7 Ah battery later on. Nevertheless, it seems that this should not be an issue because the present consumption is about 0.11 A. See the second attached photo.
