for this problem, in our user manual, there is note: D+ and D- value are just reference, not very accuracy. The product will automatically identify a device with a supported fast charging mode. At this time the device supports the QC2.0、QC3.0、APPLE 2.4A/2.1A/ 1A/0.5A、Android DCP、SAMSUNG.(Note: This quick charge agreement recognition model is not complete and for reference only, we will add other protocol in the future)
Hi friend
don’t update it now, because we did not add the update things .
now please uninstall the software and install it again to check normal function and operation
our protocol is identified by D+ and D- data, This quick charge agreement recognition model is not complete and for reference only, we will add other protocol in the future)
detection is right , it is detection by CC wire, but fast charge identity is by D+and D- value.

You have got me started on reading up on the use of D+ and D- values for various protocols, many of which are proprietary. One article with a very good explanation of QC 2.0 and QC 3.0 is Article
Do you expect to be able to implement detection of a protocol running on the CC wire in the future?
Today my TC66C arrived. Damn is it small if you see it side by side to a UM 25C. I like it!
But I hope they make a change in the Sotware. The UM 25C turns on the second you put in a device (so i can let it connected to the charger and see the current when i connect a device).
But not so the TC66. I have to manualy turn it on to see the values.
Thanks RD tech! At the moment i use the TC66C mainly to check the current draw of my QI wireless charger. It helps to find the best position on the charger.
But like i said it would help if it would automaticly turn on.
And can we logg the data when using the PC software?
thank you ,I am so happy that you like it
like i said it would help if it would automaticly turn on.—— I don’t understand
yes, you use the PC software to log the data
If i put the UM 25C in the charger and do not use it for a few hours it will turn off. When i then connect a phone, tablet. . . it turns on automaticly and i can see voltage current. . .
If i put the TC66c in the charger and do not use is for a few hours it will turn off. When i then connect a phone,Tablet. . . it will not turn on automaticly. I have to turn it on by hand to see the voltage, current. . .
HI friend
please check the screen off time, we have screen off time function, you set 0 minutes, it will be lighting
For auto screen off time setting press ‘PREV’ to repeatedly step though the 10 options from 0 to 9 minutes. Default time is 1 minutes.
Sorry thats not what i mean. If i have time tomorrow i will make a video to show the difference.
But it is only a convenience thing not a real problem.
