P25RX P25 Phase 1/2/DMR Receiver With Bluetooth Audio Support

Might have missed this post but I searched and couldn't find anything. Is there any ability to hold on or cycle through stored talk groups when connected to a car stereo?

 

[boy7777777777]

There is a hold button on the unit for the last active Talkgroup. You can’t cycle through them though.

Is anyone having issues writing Talkgroup to the p25rx? Example....manually entering the talkgroups into the software on the computer then hitting write talkgroups. Then hit make backup. Next time the p25rx is plugged into the computer the newly entered talkgroups are missing. I’m using windows 10 and firmware version 2020-06-29 19:02.

Are you giving time for the receiver to write and come back up? I have noticed this delay too but haven't minded it at this time. What it grabs, I just rename and write back.

 

[boy7777777777]

Yes. I’m giving it time. That’s what I’ve been having to do also.

I am just thrilled with the fact that SOMEONE is developing NEW hardware and software that isn't the "same old" tired design with a new front grille.
I'm putting my money where my mouth is. I bought one out of funds in my own pocket. I'm willing to give it a chance. We need to support local home grown businesses and developers who are putting effort in doing something forward thinking for their fellow radio enthusiasts. They have to eat and pay bills too. I'd much rather that profit go to feed someones' family or put their kid thru college than "Lumberg's stock go up a quarter of a point..."

Ditto. I administer a single-site (non-simulcast) system, but we've still got a need for receive-only applications without tying up a $1000+ radio which could be put to good use elsewhere. I may have to give this a try myself.

Question for BTT: Is there a possibility in the future of a simple front end iPhone or iPad app (even HTML5 based) which will allow one to view what's being received and do simple stuff like scan, hold, etc?

 

[boy7777777777]

Just use teamviewer. I use it on it now and a it works fine.

There is a new software / firmware update available. Much of the receiver firmware has been re-worked for improved performance (especially in the worst simulcast areas). Initial reports are that there may still be room for improvement when operating mobile, but that fixed location operation is very solid now. The mobile issue may have already been resolved, but more testing is needed. A new constellation view has been added to aid in diagnosing issues. The next release will likely contain some more diagnostic views underneath the constellation. I'm looking forward to feedback on this release.

The firmware update is in version 2020-07-12_1240 available on the website. BlueTail Technlogies

Any word on when more units will be available for purchase?

Let me know if you continue to have issues with this in the new release.

Assembly will likely resume tomorrow. It shouldn't be too much longer before more units are available.

Not through the Bluetooth interface. There is a hold-talk group button with a flashing led indicator to let you know when you are following a talk-group.

In theory, this could work with Bluetooth. The device does currently display the RSSI / Talkgroup over Bluetooth AVRC, but the only panel displays known to work right now are a 2016 and 2017 Honda vehicles (most likely newer Hondas). It may work with other panel-display devices, but none tested (not many have been tested). The audio over Bluetooth works with every device tested so far.
[edit] I will also point out that the configuration software is open-sourced. This may help to inspire others to write phone/tablet based software in the future.

This is great! I understand constellation diagrams with regard to complex modulation schemes (used to use Vector Signal Analyzers quite a bit back in the day) so this is a nice diagnostic and analysis tool to have.

@btt hey guy. I'm a little anxious to get my hands on one of these fancy devices. Is everything alright? Are you and your family healthy? Just making sure I'm not coming across rude or obnoxious. Just anxious.

If you follow the website for the product you will see exactly what the status is.

You mean this one that says there's no products? So what did he stop producing them? Sell the design? Did Uniden come shut him down and that's why there's no products? Then why are you chiming in? Tell me all about it. At least I had some concern. Maybe he needed somebody to express some interest in his invention because there's been zero activity on this post for weeks thinking it was a waste of time and resources?

Oy.... P25RX Digital Police Receiver With Bluetooth Audio Support

Edit: And the answer is right there in the link you posted...."moved to BlueTail Technlogies". Don't worry, the new batch is coming. I want one too and I've been checking daily.

I was just going to wait until Monday before posting here, but since you asked... I will have more available on Monday 8/3. I will extend the promotional pricing for 2 days. There will be an e-mail sent to users who signed up for notifications when they are ready to ship.

Just grabbed mine, with the 850 MHz antenna option. Thanks and looking forward to all of the possibilities it offers. I'll be glad to be a DMR crash test dummy for you also when the time comes.

 

[Mike_G_D]

Pulled the trigger too.

Here we go....
