VIM1 Basic(KVIM1-B-002) Bluetooth advertising

Android9, PIE latest official release:

I am trying to advertise on the VIM1 on bluetooth. but always get ADVERTISE_FAILED_TOO_MANY_ADVERTISERS

I have read the community posts : some says it supports upto 5 advertisors and some says its only 1 and its always somehow occupied. Can someone shed a light on this . I would like to use the device as a copmanian app to my mobile app and i need to provison the device using bluetooth.
If there are better ways to do this pls shout.

My dev environment is Android/using dart
Thank you very much

@Oguz_Uncu,

You can use this patch to test it. This is the patch we modified on VIM1S.
You need to rebuild the system yourself.

@Oguz_Uncu,

You can refer to the instructions here to download the code. After applying the modified patch, build your own system. Not using our official firmware.
