Pleading for assistance with ESC/POS commands via BLE

[steve_synopsis]

I have been working on a project for a while which utilises a ESC/POS compatible BLE printer. I can get text printed fine, but cannot get any hex commands to change font, bold, underline, LF, etc. to work.

The last time I raised the topic here, there was a suggestion made but it has not worked.

For LF, I have tried 0A and 0x0A but neither works. I am assuming that there must be someone at Thunkable who knows how the BLE hex strings should be formatted and sent to the printer.

I really would appreciate some assistance as I believe that quite a few users may benefit from the ability to write apps that use printers as part of the functionality.

Thanks
Steve

@steve_synopsis I’m really sorry, this is just not an area where I am that advanced. What I know is that the hexadecimal command goes in as a string. Formatting it though, I am not sure.
