P25 Data question?

[ghost]

Will P25 clients as well as the P25 reflector pass the following?

1. Encrypted Voice
2. GPS
3. TMS Text Messages
4. Soft ID (Standard on all Motorola XTS/APX and Kenwood radios within the P25 spec.)

Thanks! Cheers

Looks like MMDVMHost is accepting the data and passing it to P25Gateway and its getting dropped. Can Data be added to P25Gateway and P25Reflector?

I’d love to. If you can provide a full specification of the Astro network protocol, I’ll do it.

Let me know if this works. Should cover Phase-I Conventional.

The protocol in use is the Astro protocol which isn't in any of those documents unfortunately. I followed the P25NX lead, and I wish I hadn't as it binds my hands.

You can donate to the project via https://www.paypal.com/paypalme/mmdvm

Thanks
