Software Works Only with Older Firmware

Software Works Only with Older Firmware

I have node.js application to read data using a DataQ DI-1110. It works fine with a DataQ firmware version of 1.09, but it fails with a firmware version of 1.17 or 1.18. These are the only firmware versions I have tried. When it fails the "Active" led turns red. This usually happens after a few seconds of collecting data. I am sampling at 1200 Hz.

Why might my application not work with newer firmware? What, if anything, has changed in the API? I could not find any release notes for the firmware. Are there any?

Thanks
