Baofeng DM-32 --> OpenDM-32

У меня возникла проблема.
Я пытаюсь прослушать канал с помощью "Motorola RAS", но звука нет. Настройки в порядке.
С оригинальной прошивкой (opengd) такого не было.
Кто-нибудь может попробовать сделать то же самое? Интересно, это только у меня такая проблема?

I just monitored some channels from a Motorola DMR system which uses RAS.  I was able to hear clear voice. 

However, the signal strength seemed weak, which shouldn't be the case, as the repeater site is only a couple of miles from me.

Thanks for the report. Motorola RAS changes the DMR checksums with a key, so a radio
without the key sees CRC errors. OpenDMR drops frames with any CRC error, while OpenGD77
is more lenient, which is probably why you heard audio there.

Could you try this: Options -> Radio options -> "DMR crc" -> Off (this ignores CRC
errors), then listen to the RAS channel again.

Please tell us:
1. With "DMR crc" Off, is there audio?
2. Does the receive screen appear, and does it show the caller's ID?
3. Is it through a repeater or direct (simplex), and which colour code / timeslot?

If it works with "DMR crc" Off, we will make voice play even when the checksum fails,
so it works without changing that setting.

Спасибо всем за быстрые ответы.

1. Нет звука, независимо от того, включена или выключена опция CRC.
2. На экране ничего не отображается.
3. Это ретранслятор Motorola Tier 3, CC 0.

Как я уже говорил, с первой версией прошивки OPENGD для DM32 у меня не было проблем.

I have noticed that while scanning DMR frequencies, the scan will sometimes skip over active frequencies.  Once you park it on the active frequency, all seems well.  I don't believe the squelch setting is active in DMR mode?

Also, I have downloaded the amateur DMR radio ID database, but when someone is talking, I only see their ID.  I don't see their name, amateur call, or any other information.

Thanks for testing.

1. RAS: "DMR crc" Off only removes the first check. Without a readable caller ID the
   talkgroup filter still blocks the audio. Please try both together:
   "DMR crc" Off AND the DMR filter set to None, then listen again.
   (Note: Tier 3 is trunked, so a fixed channel only hears part of the traffic.)

2. Scan: you're right, squelch isn't used in DMR. With a scan step time of 0 the radio
   stays only ~40 ms on each repeater frequency, which is sometimes too short to catch
   the DMR sync. As a workaround, raise "Scan step time" in the options. We will make
   the minimum DMR dwell longer in the next version.

3. ID database: which CPS (and which version) did you use to write it? The firmware
   reads the database written by the OpenGD77 CPS (radio type DM32/UV008). A database
   written by the Baofeng CPS isn't read.

Hello,

I am using OpenGD77 version E2026.07.13.01 to download the DMR ID database from "Radioid.net"  I then write it to the radio.

I am only seeing the DMR ID but no callsign, name, or city/state.  How many ID's will it hold?

I don't see "Scan Step Time" in the menu.  Do you mean "Scan Dwell"?

Thanks, this is a bug in OpenDMR, not something you did wrong. The OpenGD77 CPS writes
the DMR ID database 0x20000 higher in the flash on the DM-32 than where our firmware
looks for it, so the firmware thinks there is no database and shows only the ID.
It will be fixed in the next version; you won't need to write the database again.

Capacity depends on the text length you choose in the CPS: about 580,000 IDs with
16 characters, 320,000 with 32, 210,000 with 50.

And yes, "Scan dwell" is the setting I meant.

Thanks for all your work on this firmware!

OpenDMR 0.3.2 for the Baofeng DM-32 / DM-32UV

Open firmware for the DM-32 / DM-32UV: DMR, FM and P25, with our own vocoders, a new user interface (English / 中文 / Español) and a browser codeplug editor. Free for non-commercial use.

Download: https://github.com/va3bpf/OpenDMR/releases/tag/v0.3.2

What's new

• P25 shows the caller: callsign, name, ID and talk group, as on DMR; the caller goes into Last heard.
  
• Our CPS writes the DMR ID database (OpenDMR CPS 0.5.0, in the zip): download the list with one click or open radioid.net's user.csv, keep only the countries you want, write it. All 316,000 IDs fit.
  

Fixed

• DMR ID database: with the database written by the OpenGD77 CPS, callers showed only as a number. Names now show, and a database you already wrote is found after the update.
  
• Scan: it went past active DMR channels and never stopped on P25 ones. It now stops on both, and empty channels are scanned as fast as before.
  
• APRS: beacons without a digipeater path were invalid frames.
  
• The P25 NAC was shown twice on the VFO screen.

Updating from 0.3.x
Radio on, programming cable in:
py tools\debug\fw_update.py opendmr.bin --port COM6
Settings and codeplug are kept. New install: see docs/installation.en.md, and back up both flash chips first.

OpenDMR 0.3.2：宝锋 DM-32 / DM-32UV 开源固件

支持 DMR、FM、P25，用的是我们自己的声码器，界面重新设计（中文 / English / Español），配有网页写频软件。非商业用途免费。

下载：https://github.com/va3bpf/OpenDMR/releases/tag/v0.3.2

新增

• P25 显示呼叫者：像 DMR 一样显示呼号、名字、ID 和通话组，呼叫者也会进入最近呼叫列表。
  
• 我们的写频软件可以写 DMR ID 数据库（OpenDMR CPS 0.5.0，压缩包里自带）：一键下载列表，或打开 radioid.net 的 user.csv，可以只保留想要的国家，写入电台。31.6 万条全部存得下。
  

修复

• DMR ID 数据库：用 OpenGD77 CPS 写的数据库读不到，呼叫只显示号码。现在能显示名字了，已经写过的数据库升级后直接可用。
  
• 扫描：以前会跳过有信号的 DMR 信道，P25 信道从来不停。现在两种都能停住，空频点扫描速度不变。
  
• APRS：没有设置路径时，发出的信标是无效帧。
  
• VFO 界面上 P25 的 NAC 显示了两次。

从 0.3.x 升级
电台开机、插好写频线，运行：
py tools\debug\fw_update.py opendmr.bin --port COM6
设置和码表都会保留。新装机请看 docs/installation.md，刷机前务必先备份两颗 Flash。

I updated the firmware to 0.3.2, and still got the same problem.
I set everything up just as you said, but with no luck...
