Hytera Data Transfer application

[e0ne199]

Hello everyone, I am looking for a hytera software called "Hytera Data Transfer". Looks like it is a freeware which was distributed through this link : http://www.hytera.com/upload/resources/Software/Freesoftware/DMR_SW_DTP_V1.00.03.000.rar
however, the link is now dead. Do you have any idea about where to get this software now? Or has it changed into something else?
I really need this to do data transmission with hytera radio..any help is really appreciated. Thx before

here is the look of the software :

Not sure why they removed the free software section of the website, don't think they replaced it with anything though.

I've got a copy of it before it disappeared, here's the link DMR_SW_DTP_V1.00.03.000

thank you so much, you are a life saver !!!!

What is the speed of this? 9600 Baud or faster ?

I'm not sure of the exact speed but each slot can only do about 4.8kbps, once you account for the overhead due to the other data needed to create the packets and the error correction you'd be looking at much less. I believe there is about 2.5kbit/s for voice so other data may be the same.

Ok so same speed as i have now. I made a small app to send data over hp5xx devices with a BT connection. Works okish just looking around for a fast speed. As i am playing with mine own crc checks and other tricks to keep it working. For small files it works okish. And acks for multiple packages (frame windows) as the latency is pretty high (500ms). Are there other also doing these things ?

Yeah latency is pretty high and everything is UDP so it has all the drawbacks compared to TCP. I'm not sure what causes the high latency or what it was the last time I did anything with the data transmission. Although I think you can get faster speeds by using both timeslots at the same time, that's called "clarity transmission", from memory it also disables some other features of the radio but you'd need to check in the CPS or try it out yourself.

I found the data rates, single slot is 1.45Kbit/s and dual slot is 2.79Kbit/s, so not particularly fast.

In a previous job I had a system for vehicle dispatching when 4G signal was poor or the towers were too busy, to allow the CAD dispatcher to use the radio instead. I remember it was a giant pain and said I'd never do it again since the Hytera documentation was so bad and not easily available. You can find out a lot from random repos on Github and using Wireshark. It involved a lot of trial and error with radio settings (seeing what was the best settings to use, some features will disable text messaging), wiring, and the code on each end of the link.

I'm not 100% sure there is much need for sending files but this is pretty similar to how SCADA systems work, instead they generally just send and receive serial data so is a bit easier. I don't think I've heard of any non-commercial data transmission systems so the documentation is very limited and impossible to build on what others have done.

I have it pretty good functional. Was a lot of probing and testing with settings and got it reliable. It is for a team awareness kit for events. DMR is just one of the transport methods of the data. It also support meshcore and meshtastic and soon also Motorola. It is now targeted for non-commercial events.
