Difficult To Connect Thermal Printer via Web Bluetooth

ngx-translate not working on production after upgrade to Angular 11

QUESTION

Difficult To Connect Thermal Printer via Web Bluetooth

Asked 2021-Jun-14 at 10:38

Right now I am developing web which has ability to connect thermal printer. I am using angular framework, and I successfully connect the thermal printer with USB using library ng-thermal-printer. But I want to my web also being able to connect thermal printer via web bluetooth which is BLE (Bluetooth Low Energy). As far as I know, BLE has specification in term of GATT and has services and characteristics in it.

The progress I did so far, I can connect and send a value to the thermal printer device in a Service and a Characteristic, let's say Service with UUID AS and Characteristics with UUID AC, using my android phone with the help of application named nRF Connect. Targeting Service AS and send hexadecimal value at charateristic AC make me successfully print something on the thermal paper.

But there is a problem. After knowing the right service and characteristic. I implemented it in my project. But, my chrome browser console showed error:

Origin is not allowed to access any service... and it told me to add optionalServices when requestiDevice()
After I added Service AS in property optionalServices, the console showed error DOMException: Connection failed for unknown reason. The errors showed both in chrome PC and chrome android.

NB:

I have enabled Experimental Web Platform features on chrome
I have enabled Use the new permissions backend for Web Bluetooth on chrome
I have enabled Allow invalid certificates for resources loaded from localhost. on chrome
I have enabled Enable new USB backend on chrome
I have used https.

Additional question. is bluetooth connection that application nRF Connect used different from BLE? if so, why it displays services and characteristics?

I'd recommend you try sending those hex values directly from the about:bluetooth-internals page and see if you can reproduce the connection error from there as well. See https://web.dev/bluetooth/#tips

If so, check out https://www.chromium.org/developers/how-tos/file-web-bluetooth-bugs to learn how to properly file a chromium bug so that the team can fix the underlying issue.

If not, could you share your JS code so that we can help you diagnose what could be going wrong in your code?
