[help] Help with nice!nano alternative

Hi, i recently bought some nice!nano alternative from aliexpress . Also a corne chocoflan PCB. I saw that the microcontrollers should work fine from this github page. I soldered them to the PCB with all the others things (buttons, battery etc.). After i flashed the software and tried to connect to the laptop, no devices appears in the Bluetooth menu, and while on wired no keypress is detected.

My question is how to you work with a Bluetooth microcontroller? How to check if the Bluetooth doesn't work, or the keypresses, could I debug the software on the microcontroller?

First question - while connected to PC - did you reset it? (two times press reset quickly, or connect RST pin two times quickly).

First of all, I am not sure the zmk firmware you picked up is compatible with chocoflan.

By default, the left-hand side is connected to both a computer and the right-hand side while the right-hand side connects to only the left-hand side.

I haven't tried the clone from Tenstar Robot yet and not sure their board fixed the battery drain issue.
