IBS-TH2 data sheet

Can we get a data sheet for IBS-TH2 communication? I’d like to take readings on my server manually.

Sorry, the data of IBS-TH2 can only be exported through the Engbird app. We currently do not provide the data sheet for IBS-TH2 communication.

Any particular reason for this? We just need to know which handle to call using something like gatttool.
