What happened?
I have defined uart1: and uart_channel1: in config files. But Offline controller is not connecting. I have tested 2 years back, does it changed something in recent versions?
GCode File
No response

I am using the controller came with machine. It has ESP32 with 3.2inch TFT. One other which is made by me ESP32 4.0inch TFT. Both were working with FluidNC I have tested earlier (2 Years Back) Now a days I was using LinuxCNC so didnt tested. Now That setup broked.
Earlier it was working on earlier versions of FluidNC. Nothing changed since then, only the change is latest FluidNC.
I found a photo that shows a FluidDial connected to a pibot. Is your pendant based on FluidDial? The supported FluidDial variants use M5Dial and 2.8" CYD displays. We do not have schematics or software info about variants of the display sizes that you lost above.
I see that you have the uart1 baud rate at 115200. The baud rate for standard FluidDial software is 1000000, I.e. 1 megabaud. But since I do not know the details of your non-standard pendant, I cannot say if 115200 is correct or not. We need complete information to solve problems.
Uart channel is created as displayed in FluidNC msg using gpio 25 as tx and gpio 27 as rx. It's standard offline controller which comes with Chinese 3020 type CNC. And it's available as separate also. It has +5v, GND, rx and tx pins. It sends g-codes via uart channel. I have one diy offline controller also which also based on esp32 and TFT display.

It was working in previous versions of FluidNC. I used to connect at 115200. Tried at 9600 also.
