This is the information we got from HLK developers:
Also your previous feedback on the app is being updated, it was going to be released together, too late for development. the app will lag by two weeks at that time and will be compatible with the new 2412 as well.It's still in development, several new products have been developed and launched recently.
Also added: hang test mode. After opening the module automatically records the trigger someone's moment of motion and static energy value, through the app can read and display the energy curve at that time, convenient for users to hang test debugging.
