Hi,
I have several HLK-LD2420 modules, but with different firmware versions, such as 1.6.2 and 1.5.9, which act differently sometimes, for example, in "OUT" pin behavior! Now I want to know how I can get the latest firmware to upgrade all modules to the same version?
Regards
Ali

Hello,
Thanks for your answer.
I have several modules with 1.5.9, how can I update these modules? How can I get the 1.6.2 files for the update?
I do not have the firmware file to update! how can i get it?
Regards
Ali
Hello, Sorry for the mistake in my last message. The latest firmware version is 1.6.1. Please follow the steps below to upgrade it.
Open HLK-LD2420_TOOL(V1.2.1.1), 
1→Connect the device
2→Update firmware
3→Get the firmware infos
4→Select the BIN file path (choosing the latest firmware )
5→Download
Hello Support.
I am also looking for the download link for the latest firmware for the LD2420-v2.0. Unfortunately, I have to inform you that your response has not been sufficient so far.
The HLK-LD2420_TOOL software can install the firmware on the LD2420. That is the "Download" button you mentioned above. The download button is not for downloading the firmware. When you press the button, you must already have selected the firmware.bin file we are searching for. And this file cannot be found in the HLK-LD2420 section of the above-mentioned download link at https://h.hkltech.com/mobile/download.
What all users here need and are looking for is the file with the firmware that has the extension .bin.
Best regards from Germany,
Gabriel
