i8000 TMC driver development

Hard to answer, what The HyperGPS Client said regarding the TMC Status?

It says: "TMC driver active". But when I try to test it, it gives me an error: "cannot open com port. Is the driver loaded?"

reactivating the driver by pushing the TMC button doesnt solve it. Only a softreset helps.

thnx

Solved see above

I tested V1.8. My impression is almost the same as in V1.6.

Many stations will be skipped with a good antenna. Otherwise, it works!

Some radio stations say TMC, and after several seconds: CA-TMC (no code). Is it TMC PRO (pay TMC? D,A,CH) Can we use it, perhaps with your DLL too?

Thanks for the report. The CA-TMC message I never seen, just know that the navigation program must have a transfer table to translate the event and position numbers to coordinates and traffic event type which can display. So in the case you have a pay TMC radio station, I think nothing to do in this layer...

Have seen the CA-TMC message too, think in v1.7. Maybe thats an issue with german radio stations. Tried brand new v1.8 even if I get hardly a RDS signal, but to make a long story short - it works! After 20 min I had a lot of messages in iGo with auto seek on! As antenna I used the headset cable without earphones. By the way, I tried since v1.2 but due bad reception never got any TMC message before even with fixed frequency.

Thanks phj for your effort and sharing the result!

Update:

Awsome! I tried to gain reception with a better antenna (headset with 2.8m cable, lying in one loop). Right after switching in iGo to the navi screen the TMC symbol glows. Some seconds later I got the mail letter. While scrolling in the TMC screen new messages arrived one after the other. After 5 min the flood fade away and I had 4 pages of notifications.

Now it's time for a programme to replace the antenna... ;-)

To clarify the Pay-TMC problem: First of all, I have no real knowledge about that, but I think the RDS is standard, so every special thing must do within the standard. This means that TMC is a special type of RDS message ( block 8A ), and the content is the same, so the main part is the event ( what happened) - 0-2048, and the location (where) 0-65535 , etc.. As you can see, anyhow must use some conversion table to get the exact information from this RDS messages - and this is for ex. must be different for each country.

All information I have regarding Pay-TMC that or this conversion table or the messages sent by the radio station is AES encrypted - you get the key somehow when pay for it. This means that all the work must do to decode the crypted TMC message is out of the scope - this hardware driver just collect the RAW 4*16 bits RDS data....

So the answer is yes, you can use my driver for Pay TMC, in the case you have a decoder for the cypted messages...

P.S:

Once again, I have limited knowledge, so anybody have more information, please write here.

Hi,

yes, the phj driver can be used for pay-tmc (in german tmcpro). if you see in igo CA-TMC (no code), then you have the tmcpro channel, but the wrong version of igo. the only version of igo that have a build in tmcpro code is version 8.3.2.90500. if you use the same channel as above, you see CA-TMC (code ok), and that means that you know will get tmcpro messages (even better than normal tmc messages, here in germany).

thanx phj for your fantastic driver.

Hi mate... First of all many thanks for sharing your hard work with us - its really excellent application. WIll it work without ext. antenna or I have to use earphones or at least some piece of cable I put to earphoe plug ? If it needs cable in earplug - does it affect somehow my bluetooth headset - dont know if calls will be not routed to earphones instead of bluetooth headset...

You must use antenna - but not necessary must insert the jack. If you use just the outest pin with a truncated jack ( cut at the first tag ) and a piece of cable connected to, it is enough. In this case the system doesn't route the voice, you can use the telephone as before.....

I dont exactly understand what u mean by "use just the outest pin with a truncated jack ( cut at the first tag )" Also dunno what u exactly mean by " In this case the system doesn't route the voice, you can use the telephone as before....." thanks in advance for explanation ...

What happen if you insert the earpiece jack? The sound goes to the earphone and there is a pop-up window asking what type of cable you inserted - this called by me audio routing. The truncated jack you can study here

hmmmm I prolly stupid :-). Does you mean you opened jack connector and cut one of the soldered cables ends inside connector so only one pin is used instead of two. Than I will cut rest of cable at some point so finall I will have piece of cutted cable ending by jack with one of pins unsoldered. Is that what u mean ?

Please compare the jack on the picture with your earpiece jack. You will see that the jack in the picture is shorten - this is because it is cutted . So you doesn't need to open your Omnia, just make a special jack connector...

I compared already before - all I can see its not only shoter jack - its absolutely different connector type than connector of my earphones - I have classic earphone standard stereo minijack on your picture is absolutely different connector type - it looks like connector from my 12vdc power adaptors for travelling .... Do we talking both about omnia 2 i8000 ?

EDIT: Im getting there :-) .. Its simply a piece of cutted cable from earphones ( cable doesnt lead anywhere on one end ..its cutted) and on the other end of cable is a jack with top 2 active parts of jack cutted and only the longest part of jack - ground is left. Am I right now ? btw -- from your picture it really looks exactly as multivoltage adaptor power connector :-)

Please, all the discussion regarding this special jack states that this is NOT standard, you cannot buy such. It is derived from a normal 3.5" jack; you must cut it at the first tag - therefore so short.

Yes I already updated my above post ...I realized that finally how is it :-). Just a question how long should be a cable which leads from jack to have a good reception. I assume longer cable I leave its better for reception but maybe you done already some tests..so you might gimme some tip what lenght is optional ?

The wavelength is more than two meter and a simplest antenna optimum is lambda/4, so an approx. 50-60cm cable must be enough...

PHJ, thanks, you were right... I just pluged the earpiece and iGo found the TMC hardware, but got no signal.. But i think there is no TMC implemented in my country yet...

There is TMC on Brasil, but only on SP and RJ.

Look at this

Could not test it yet as I don't live in this cities.

Anyway... thanks PHJ for this code! :)

Hi Phj,

I downloaded and ins

talled hyper gps and gfmapi from your site I also already copied HGP switch to igo program dirctory but now I dont understand what to do - what u mean by "make a linkfile named NavApp.lnk which point to your Navigation program (for ex. iGO8.exe)" ? How do I make .lnk file and why I need it ? thanks in advance..

So again: if you have iGO, copy the HGPS_Switch.exe to the Program Files/iGO8 folder, and make a Navapp.lnk file there ( use RESCO explorer or similar file manager) - as the name suggests, it is a link file, which must point to the iGO8 executable file. This is needed because when you start the the HGPS_Switch progam, it will automatically load the gfmapi.dll and HyperGPS.dll and after start the program which to NavApp.lnk points to.

I have iGO8 on my Omnia2 (VZW i920) and thought the RDS would be pretty neat... Installed HyperGPS Beta9 and then PHJ's gfmapi.dll cab file. I then configured HyperGPS for Com 2(Also tried Com 8), TMC data, Royaltek output and enabled TMC. I click on Test and tuned to my local TMC data station of 95.7 and validated I get TMC and also stuff is flying by on the input. I have headphones connected to the jack.

I launch iGO8 and go into the TMC Settings. I set to Realtek and COM 2 or COM 8, even tried all AUTO. and I never get it to recognize. Every time I get "No TMC Harware Found" when I hit Autodetect.

Additionally, I configured HGPs_SSwitch.exe by creating a NavApp.lnk link to my iGO8.exe and placed the HGPs_SSwitch.exe in the same directory. Launch HGPs_SSwitch.exe and my assumption is that it will launch iGO8 after enabling the driver and then when I close it will disable the driver... but my iGO8 never launches.

TMC would be great but I just cannot seem to get it to work.

Anyone else have an Omnia 2 i920 and been able to get this to work? Or is this only for the i8000 version of the Omnia2?

UPDATE: Changed protocol from Royaltek to GNS and it works correctly.

Hello. I have started PowerRadion, overwrite de gfmapi.dll in program files/powerradio but when a run a full scan of the radio stations, I get this error message when it tries to receive the radio name over rds: PWER RADIO PANIC: ScanBand unknown reason=83.

Can anybody help me with this one?

Thankyou
