I also have a device that works as a TK-102 (or at least one of the three I have). The last 2 I order simply doesn't work. I only get the following message, even if the vehicle is driven:
0000 23 23 2C 69 6D 65 69 3A 33 35 39 37 31 30 30 34 ##,imei:35971004
0010 37 30 30 31 36 37 33 2C 41 3B 7001673,A;
SMS commands and the general setup is exactly the same I used for the initial one, but with no luck. Its probably noteworthy to say the first one that's working was ordered almost a year ago, and the latter two only about 2 months. So there might be some firmware/in workings that has changed. The devices' info is here: http://www.dx.com/p/...sitioning-29284
Any help will be appreciated!
So eventually I got it to work, no idea how though, but nevertheless it's working as a tk102. The one thing I did differently is send commands nosuppress and less gprs off. If I enable any of these two, the GPS disconnects after a couple of minutes and I get no positions anymore. I really wish to use these to same data, as it's working on my other unit. This is very strange and frustrating.
