Hello, I believe some friends have discovered that “there is a new version of TK905/TK905B 4G, Type C input, and the original protocol has also changed to JT808.” And wondering how to get the device online!
Here is a solution:
The new version TK905 4G uses the JT808 protocol.
You can choose the Huabao protocol, but you need to add one or two “0″ in front of the 10-digit ID number.
Then it will work.
Hopefully my answer is helpful to you!
