Hermes GPS Development v2

Hi,

Now that there is the TyTN II with GPS.
Isn't it possible to use the RadioRom of the TyTN II on the TyTN to get the GPS chip working?? (with some hardware modifications? wiring the GPS module to the antenna?)

No - 2 different Chipsets.

No - 2 different Chipsets.

There is no connection. Hermes uses Samsung chipset while Tytn II i.e. Kaiser uses Qualcomm. Keep using BT GPS mate.

No, Hermes uses Qualcom chipset too (but the other version than TytN II.). CPU is Samsung, but radio chipset Qualcom with some other components.

I though so to :o

Speaking as one of the participants in the original testing threads and from memory:

Could GPS be activated through radio? Yes.
Could GPS NMEA output be routed through the OS? Yes.
Could we get a decent enough signal to make it viable? No.

Final bit seemingly because of the layout of the hermes it became highly impractical to get a working mod which attached the aerial to the chip.

After all this I got myself a Navicore Slim (Holux in disguise) and went the BT route. It's the only decent way to go with the Hermes, and it's pretty good.

Theres a thread where they went to the level of taking the phone apart.
Correct me if I am wrong here but they found that it had been purposely disabled by means of not attaching an aerial and because its a surface mounted chip its nigh on impossible for anyone to make the hardware modification required without breaking the legs on the chip.

So for all intents and purposes GPS is not possible on the Hermes without an external GPS receiver
