Hi, I had a problem with CB module, I can’t flash program.
I connected Tx module - Rx USB, Rx module - Tx USB, GND and 3.3V
I’m using USB TTL CH340 and BenKen WriterV1.60 to flash.
Have anyone ideas? Thanks

I assume you are using ESPHome? Please tell us more about your issue - what you have tried, what any error messages are, any log files. Otherwise we are just guessing.

Hi, I don’t use ESPHome. I’m just testing the CB module, as I have a project related to it. I built a test program, and now I need to flash it.

Then you are in the wrong forum - this is for Home Assistant and ESPHome.
There may be someone who has experience flashing on the LibreTiny platform using BL72xx chips and may be able to assist, we can only hope…
You probably need to touch the CEN pin to GND to put the module in flash mode.
