GM861 Barcode/QR reader multiple SENSOR messages instead of single one...

[belveder79]

I've attached a GM861 barcode reader and enabled

#define USE_GM861
#define GM861_DECODE_AIM 

and it works nicely for simple barcodes. However, for barcodes with more content, it gives me a multitude of messages instead of a single one.

08:21:06.442 RSL: SENSOR = {"Time":"2025-05-15T08:21:06","GM861":{"AIM":"QRCode","Code":"{"type": "AR4LO"}}
08:21:06.463 RSL: SENSOR = {"Time":"2025-05-15T08:21:06","GM861":{"Code":"GIN","domain": "ku"}}
08:21:06.484 RSL: SENSOR = {"Time":"2025-05-15T08:21:06","GM861":{"Code":"enz","username": ""}}
08:21:06.505 RSL: SENSOR = {"Time":"2025-05-15T08:21:06","GM861":{"Code":"kuenz2","password""}}
08:21:06.521 RSL: SENSOR = {"Time":"2025-05-15T08:21:06","GM861":{"Code":": "123456"}"}}

I could not find information about that in #18399 so please advise what I'm doing wrong here. Thx

ok, learning it the hard way... it's about the BaudRate setting in the GM861 driver and the read window of the serial port...

This separates the read into chunks. problem for an application is that you need to enable AIM in order to be able to "reassemble" the real read from multiple reads, as the AIM can be used as a "start flag" and whatever comes next without an AIM flag has to be combined...
