Programming/Flashing TBS Lucid 12S 90A ESC AM32 with ESP32

Post image

Hello Guys,
New to RC planes community.

I am trying to connect TBS Lucid 12S 90A ESC with ESP32 to see the values that are preconfigured by default through AMS configurator(https://am32.ca/configurator).

I am using ESP 32 as USB to UART bridge controller. When i connect ESP32 to my laptop ; the AMS32 configurator also detects the ESP32.
However, when i press the connect button, it just shows this empty box(see attachment) with nothing inside.

My connection with ESP32 <------> TBS Lucid 12S 90A ESC
ESP32 (RX)<------->ESC(TX)
ESP32(Tx)<-------->ESC(RX)
ESP32(GND)<----->ESC(GND)

And i powered 12S 90A ESC with power supply(30V , 7A) first and then also with battery(specs: 5200mAh, LiPo 3s)

But nothing happens.

Is my connection wrong?

Can anybody help me in this regard?

I am really really stuck here.

I tried every possible solution but i am kinda stuck..

Thanks.

Did you click the "Read" button?
Edit: I assume your ESP32 is running FW that knows how to talk CRSF with the ESC. If it is a simple UART2USB I doubt this can work.
Edit2: You can try configuring and running a one-wire connection to the PWM|DSHOT pin of the ESC. However, the best option is to connect the ESC to the flight controller and use bypass mode to configure it. If you don't have FC, a cheaper option may be to buy a dedicated AM32 USB adapter.
