RD-5R Cannot connect to radio
Re: RD-5R Cannot connect to radio
Are you sure you are using the correct cable? The RD5R cable is wired differently to the GD77.
Re: RD-5R Cannot connect to radio
The UV-5R cable does not work with RD5!
Re: RD-5R Cannot connect to radio
In firmware update mode the radio enumerates as a USB HID device. look in the device manager and child check a new HID device appears when you plug in the radiokengreen wrote: ↑Sun Feb 05, 2023 12:14 pmI have a DM-5R radio that I am trying to update. it has OpenRD5R firmware from Oct 16,2020 ce0e010. I have tried OpenGD77 software but cannot connect to the radio with the cable I got with the radio. It will go into programming mode by turning on with the two side buttons pressed, No display and green led on. Device manager shows Com port 3 open but not OpenGD77. I need help

Update the CPS to the latest versionkengreen wrote: ↑Wed Feb 08, 2023 11:47 amWith the radio connected in programming mode (dark screen, green led), I have 4 HID devices listed. Without the radio I have 3. The new HID device is not labled but has port 0012 and hub 0001. how do I connect the radio to the computer using the new HID device? the software, OpenGD77, only allows COM port. Do I need to specify the port and hub in the .config file? Assuming that I can connect the radio to the computer software, I need to update the firmware and change the channels, talkgroups, etc
The update the firmware to the latest Beta
Then use the CPS to update the channels etc

Hi, I get this but its the RD-5R sockets. I need to strip it down and resolder them. Giving the plug a little wiggle fixes it.
Re: RD-5R Cannot connect to radio
Hi,
I have received today a new Baofeng DM-5R.
And it was in the box a USB cable.
Tried original software to read radio, even in COM 1 but even CPS cant mske good connection to the radio.
Cant read it, so cant programme it.
I wold like to update for opengd77. Like i have done for my retevis rt3s. But how i csn do it, if it says cant findvthe radio?
Can you or anyone help?

Re: RD-5R Cannot connect to radio
1. COM port is not used for firmware uploads. In bootloader / update mode, compatible radios are a HID device
2. Only DM-5R MK2 Tier 2 is supported. I did not think DM-5R was still manufacturered, I thought Baofeng renamed this radio to RD-5R. Hence see the information on this site that only RD-5R is supported
If you radio is a Tier 2 DM-5R then just put the radio into firmware update mode, by following the instructions in the OpenGD77 User Guide and use the OpenGD77 CPS to install the RD-5R firmware
However if you radio is not a renamed RD-5R then it can't be updated

Re: RD-5R Cannot connect to radio
I recently purchased a DM-5R on Aliexpress. It was advertised as "2019 Model"... It is Tier II. I just finished updating the Firmware and doing a Read/Write to the radio from the CPS. All I can say is it all went without a glitch... After I found the K2 plug was not fully seated! I kept trying the FW update and the OEM CPS and was frustrated the radio would not connect... DUH!
Haven't written a full code plug yet, but I kerchunked my hotspot successfully. I can testify that OpenGD77 will install on at least some Tier II DM-5Rs. Note: Out of the box at boot up, the radio displayed "BF-5R"; I saw this in another post. No worries; just something else to confuse us. I just changed it to my callsign
Kudos to the developers!

Re: RD-5R Cannot connect to radio
I think as long as it claims to be Tier II, then the hardware should be compatible, but the whole thing about the radio displaying BF-5R is confusing, as some UV-5R's are listed as BF-5R and they are an FM only radioKD9WNR wrote: ↑Fri Apr 21, 2023 10:43 pmI recently purchased a DM-5R on Aliexpress.

Just to add to the confusion there were some Tier 1 DM-5R's produced.
So I guess its buyer beware, but if you can pick one of these up at a hamfest for a few dollars, it may be worth the risk that its not compatible
