Hotsauce22 1 #1 Posted March 5 Since buying my own rig I have used a Yepzon one 2.0 gps tracker stowed in the d back. So that if I had a cutaway or my rig went missing while travelling, I would be able to locate it. The Yepzon has worked faultlessly , up until now. The device stopped connecting with the app in February, so it became a brick. I have tried getting support from Yepzon, without any responce. Finally I have hat a responce from a legal firm informing me that Yepzon went into bankruptcy at the end of February this year so their devices and network have been shut down. is anyone using a different gps tracker that they would recomend the ad t e we I’ll give a good degree of accuracy ?

johnhking1 40 #2 March 5 My wife has a tracker for her dog. It is about 3/4 inch x 1 inch x 1.5 inch. She can use her cell phone and track his location from any where. She was overseas last week and could tell where he was within a few feet. It came with a charger and needs to be recharged every few days. Quote Share this post Link to post Share on other sites

airnutt 7 #4 March 6 I just received a yepzon from a friend 3 months ago, no wonder it was free 1 Quote Share this post Link to post Share on other sites
sfzombie13 298 #5 March 6 i wonder if you couldn't reprogram them to use another number and set up your own cloud for it to talk to. would be worth a try. do they have a jtag pinout? Quote Share this post Link to post Share on other sites

sfzombie13 298 #7 March 14 open it up and take a picture and post it here. i can look and see if it has any connections i can tap into on the board. you may not be able to get it apart without breaking it. i'll do a search and see if anything comes up. someone has probably done it if it can be done.

sfzombie13 298 #9 March 16 i don't see a jtag connection but it looks like you could reprogram it if you knew how. you'd need some way to attach to the chip. some of those test points may also be the jtag and it just isn't labelled, some companies do it that way. i'm gonna look it up since i now have numbers to put into search engines. thanx for the pics.

That's a Qualcomm chip there - could be the main chip, or at least the cellular modem. You'd need a few million dollars and some pretty stringent NDAs to get any documentation from Qualcomm on how to program it... 1 Quote Share this post Link to post Share on other sites

You'd need a few million dollars and some pretty stringent NDAs to get any documentation from Qualcomm on how to program it... that's not what you need to program, the os or whatever runs it is what needs programmed. qualcomm has pretty good documentation on their chips and what the pins do, but they look real hard to get to the way they soldered the chip on the board. but it's hard for me to tell a lot from a picture because it isn't my specialty, just something i know about. i've done it before on other devices and could probably figure it out but maybe not. now going into the qualcomm firmware, you're right, no way to do that i could ever figure out anyway.

Chirita 0 #12 March 17 Can this one be also fixed with a network provider since the sim is embedded on the motherboard ? Like giving them the IMEI number to activate it on their network! It uses a M2M-SIM-OnBoard (MFF2 size standard), cannot be changed by the user Quote Share this post Link to post Share on other sites
sfzombie13 298 #13 March 17 i have no idea how that works. like maybe straight talk so that you don't have to pay for it until you need to use it. i'd give it a try. i'll bet you can pick those trackers up cheap if the company went out of business.

MickPatch 40 #15 March 29 The assets and technology of Yepzon have been acquired by another organisation, they expect service to be resumed for existing devices. Indeed this morning my Yepzon briefly checked in to the system before the connection was disabled again, probably some service testing is being run before a re-launch announcement Quote Share this post Link to post Share on other sites
