Is it possible to coonect BGX13S22 to BlueTooth COM port of a PC (Win64)?

No. The WT12 is a Bluetooth Classic device and BGX is Bluetooth Low Energy. The serial port profile is only supported on Bluetooth classic, there is no equivalent GATT profile or service on Bluetooth Low Energy.

Have you considered the BT121 instead?

Series 1 and Series 2 products are done using different fabrication processes and that is what brings the significant reduction in active current consumption (RX/TX and uA/Mhz on the CPU). Range is a function of the link budget (TX power - RX sensitivity) between two devices and it's not affected by the current consumption on neither of them.

Some more info.

2. Is there an API reference manual for the bluetooth stack 3.0? because the only version I find is the 2.13 one.

https://docs.silabs.com/bluetooth/3.0/

3. Is there a client-server SoC example for the new 3.0 stack? Because it's pretty different from the 2.13 one, like the management of the calls at start up and the bluetooth init.

You can find soc-thermometer and soc-thermometer-client sample apps in the SDK which are now using the new API and the new code structure, those are the best reference.

The Bluetooth audio offering that we have is only on Bluetooth Classic but unfortunately those modules are now in NRND status (not recommended for new design). There is really nothing else that we have which can fit your use case.

No, but there is something from the community which you can 3D print: https://www.silabs.com/community/projects.entry.html/2017/08/20/project_completedan-3RvH#M570

Am I right that BG22 modules (not SoC and not Kits) are not supported in SS v4?

You are mostly right. The BGM220 modules were only released on SSv4 (GSDK 2.7.x) as alpha quality to get some of our alpha customers going with development. It was never fully released on SSv4, only on SSv5, so the official recommendation is that you start using SSv5. You can find this information in the release notes: https://www.silabs.com/documents/public/release-notes/bt-software-release-notes-3.0.1.0.pdf

Is it still today the case that BT Mesh is not supported on 256K parts like the BGM121?

Yes, the parts with 256K of Flash do not support BT Mesh.

Are you on Studio v5 and have you updated the Bluetooth SDK to the latest patch 3.0.1? If so then the kit should be automatically detected when you plug it into your PC.

I can see the example just fine. Creating and building also works fine for the part, as well as the radio board (BRD4312A).

The issue might be that you updated studio but didn't update the Bluetooth SDK yet. Go to the Installation Manager, then Manage Installed Packages, SDKs tab and select Bluetooth, you should see 3.0.1.0 SDK ready to be installed (in my case it's installed already).

 

Hi Bert,

This is a known issue which is documented here: https://docs.silabs.com/simplicity-studio-5-users-guide/1.0/getting-started/overview/#known-issues
