Unable to connect to MTP-II

[zejtin]

Hello!

I have an MTP-II printer which should be fine. Name on bluetooth is MTP-II_BC6A
I am trying to scan it with tpScane((char *)"MTP-II_BC6A", 15); to no avail, tpScan returns false but printer changes led color to blue like when it is connected when running tpScan.

Any info on this?

Thanks in advance

use library version 1.1.2. It should work when you scan tpScan((char *)"MTP-II_BC6A", 15);

Tried it just now, it still doesn't find it, difference with 1.1.2 is printer doesn't show there is connection as with the latest one

Your code line in the above post reads "tpScane((char *)"MTP-II_BC6A", 15);".........It should be "tpScan....".

My bad on that, it is tpScan otherwise it wouldn't compile

I ended up writing my own code without the Thermal_Printer library. I used arduinoBLE library and scanned for UUID. Everything works fine that way, but you'll have to hard code the esc/pos commands.

Sorry I can't help more.

Do you maybe have some repo or example how you did it?

To add a new printer name, truncate it to 9 chars and add it to szPrinterIDs[].

tpFindPrinterName() truncates the advertised printer name to 9 characters or less before looking for a match in szPrinterIDs.
