Need Help Finding the Correct SDK for Bluetrum BT167CT Chipset

vikasgadiya93

Hi everyone,

I'm currently working on a project with TWS  using what I believe is a Bluetrum Bluetooth chip with the marking  "BT167CT".

However, I'm running into a wall trying to find the correct SDK and documentation for this chip. I'm hoping someone in the community might have some insights.

• Which SDK should I use?  Bluetrum's SDKs are typically organized by chip family. For example:
  • AB530X series for basic Bluetooth audio
  • AB561X /  AB565X series for TWS earphones
  • BT892X /  BT895X series for more advanced applications
    
    
  I'm not sure which family "BT167" belongs to, if any.
• Where can I find documentation?  Datasheets, reference schematics, or any technical docs would be incredibly helpful.
  
  
  

I already have with me - downloader , testkit and TF card

My goal is to OTA upgrade

Thank You
