Connecting stuck

[Tibiiii-15]

Hello, I downloaded the bin file and uploaded it, but it's taking a very long time to connect.

I use this, everything is connected properly, there is an LED in the corner for lighting, but there are 2 in the middle and the one on the right flashes, the left only sometimes. Also, at the very beginning, the two middle ones were constantly lit up.

Please make sure your dongle is set to 3.3V and you have pin0 shorted to GND.
Could you please send a picture of your wiring?

Sorry for the delay here... it has been quite busy days. 😞

It's hard to see in your picture which pin is what in your TTL dongle. Just make sure you have this schema:

Panel's Board	TTL USB-to-Serial
3V3	VCC, 3V3, or 3.3V
TX	RX
RX	TX
GND	GND
IO0	GND This can be connected to a GND pin on the panel's board.

Please note that TX & RX are inverted between your panel and the TTL dongle.
It's also important the you do not power the TTL (do not connect to your computer) until the wiring is done, as the ESP32 won't enter in flashing mode if not connected correctly at power-on time.
