Hi kruch,

First of all, thank you for this great application. I'm using version 0.9.81 now for a little over a year for Geocaching and I'm really happy with it Smile

I've tried to send a location SMS from a phone that is not running Trekbuddy to another phone that is running Trekbuddy. This SMS is received as a normal SMS and not not recognized by Trekbuddy. Confused

Is it possible to format an SMS in such a way that it will be recognized as a Trekbuddy location SMS?

If that is not the case, how could I send a location SMS from another phone or specially written application so I can receive a location SMS from someone else not using Trekbuddy?

Best regards,

wega51.

Unfortunately - as far as I know - this is not possible: midlets do not have access to "ordinary" inbox, it is prohibited by the specification, but they can listen on a "private" inbox identified by port number. TrekBuddy is using port 16007. The port number can be specified in URL when application sends SMS.

By the way, I will soon change the format of the location SMS to that used by Garmin XT application (available for symbian, windows mobile, palm) - the format is more human readable, and compatibility with another app is often a good thing, even more when it is a company like Garmin.

Hi kruch,

Thank you for your fast reply. I think I will try to write my own application and see what is possible. The port number seems to be the missing information (if only I could remember where I found the description of the exact format of your curent location SMS Rolling Eyes

) .

Anyway, keep up the good work! I'll be monitoring your progress...

BR, wega51.

When I was defining the format I had no better idea than to mimic NMEA sentences, but it really did not turn out to be a good choice (proprietary and not human understandable)

$TBMYT,1179735361,5000.29965,N,01749.65780,E,Be quick*00

* header $TBMYT or $TBIAH - TrekBuddy My You There or I Am Here
* timestamp in secs (currentTimeMillis / 1000)
* coordinates in the same format as in NMEA
* user message (ie. "Be quick" in this example)
and end as NMEA (*00), but checksum is not implemented

I know how this issue is solved by commercial gps software vendors. They do run separate native SMS proxy on the phone which forwards ordinary SMS received to custom port SMS needed by java application and vice versa.

Another idea is having raw NMEA sentences GPRMC or GPGGA or any other...
In that case it will be easier to make a software send an sms that can be recognized by the TrekBuddy.
Or maybe having all of the above....

Just suggestions!

The software is perfect until now and keep.....walking!!!
