I've tried to upgrade the firmware from two of my HLK-LD2460 modules via the official HLKRadatTool Android App, at first it looked that it went ok, and the firmware version changed from V1.3.2503 to a newer version.. but as soon as I tried to reconnect, the app did find the module in the start screen:
but when clicking on it, the screen hangs a while showing a "Please later" message, and finaly it shows a "Data transfer timeout" error:
Also when I try to connect via the "HLK-LD2460 Tool" on my laptop, it does see my module connected to COM6, but also there I'm not able to connect to it, I tried all different Baud rate (in case the Baud rate somehow got changed during upgrade)
I'm not able to flash the module anymore via the Android app.. does anyone know where I could download the (top) firmware for the HLK-LD2460 so that I could try to flash it back to the older firmware? Or does anyone know if there is a way to get the modules responsive again?
