Baofeng DM-32 --> OpenDM-32

Many thanks to all the developers

I just upgraded to version 0.2.0, and now DMR (and AM aircraft) is working fine. 

However, in the OpenGD77 cps, if I select "AM" as the mode for aircraft frequencies, they come up as "DMR" on the radio itself.  However, I can then change them to "AM" mode in the radio menu, and it works.

Check Radio info, see if it also show full charged

ok

Any chance to add a nuisance delete for the scan function?

Are 4FSK calibrations used?

OpenDMR 0.3.0: P25 on the Baofeng DM-32UV

OpenDMR is open firmware for the Baofeng DM-32 / DM-32UV. Version 0.3.0 adds APCO P25 Phase 1 digital voice:

P25 mode for channels and VFOs (SK1 + *), with the NAC and talk group
Simplex group calls in the clear: DM-32UV to DM-32UV, and received by MMDVM hotspots (Pi-Star)
About 250 ms from PTT to the other speaker, quicker than its own DMR
Our own IMBE vocoder and air interface, with no stock firmware code
Also new:

Power up to 10 W, set for each channel and VFO
OpenDMR CPS in the package: a codeplug editor that opens in Chrome or Edge. It writes Chinese names, P25 channels and the radio's settings.
Download and docs: https://github.com/va3bpf/OpenDMR/releases/tag/v0.3.0

For now it does simplex group calls in the clear only; encryption, private calls, repeaters and trunking are not done yet. The known issues are listed in docs/p25.md, and help is welcome. Non-commercial use only.

OpenDMR 0.3.0: P25 on the Baofeng DM-32UV

Thank you! The frame are being decoded...

In version 0.3.0, it seems that the squelch isn't working properly in the VHF AM aircraft band.  After a transmission, the squelch remains open.  When you adjust it, it's fine until another transmission; the squelch remains open after the transmission is over.

In version 0.3.0, it seems that the squelch isn't working properly in the VHF AM aircraft band.  After a transmission, the squelch remains open.  When you adjust it, it's fine until another transmission; the squelch remains open after the transmission is over.

Thanks for the report. From the code, this looks like the AM squelch hysteresis: the squelch opens at the set level but only closes 3 dB below it, and one squelch step is also 3 dB. If you set the squelch to the point where it just stays closed, the noise floor ends up between the two thresholds, so once a signal opens it, it never closes again.

Could you try this to confirm?

Turn the squelch up until it just stays closed (no signal).
Turn it up one more step.
Wait for a transmission and see if the squelch closes when it ends.
Please also tell us:

Does one extra step fix it, or do you need two or more?
When the transmission ends, does the signal meter on the screen drop back to where it was before?
The squelch percentage, the frequency, and whether your radio is the DM-32 VHF or the DM-32UV.
If one extra step fixes it, that's a workaround for now. We'll fix it in the firmware so the "just closed" setting works without losing the extra 3 dB.

Check PM...

va3bpf, I am unable to replicate the AM aircraft band squelch issue.  I am scanning a group of AM mode aircraft frequencies, and it's working just fine now.  I don't know what might have changed between last night and today. 

I can also confirm that P25 TX and RX is working. 

One thing I would like to see is a nuisance scan delete.

Я успешно установил прошивку, пока всё работает нормально.
Есть ли возможность реализовать пароль для включения устройства (power on password), как на оригинальной версии opengd77?

OpenDMR 0.3.1 for the Baofeng DM-32 / DM-32UV. 中文说明在下面。

Downloads
OpenDMR-0.3.1.zip: the firmware (opendmr.bin), the Chinese font (cjk.bin), our codeplug software
(opendmr-cps.html), the tools, the installation guide and the user manual.
opendmr-cps.html: OpenDMR CPS 0.4.0 on its own: open it in Chrome or Edge, nothing to install.
SHA256SUMS.txt: certutil -hashfile OpenDMR-0.3.1.zip SHA256
Updating from 0.3.0: keep the radio on with the cable plugged in and run
py tools\debug\fw_update.py opendmr.bin --port COM6. Settings and codeplug are kept. The Chinese font is unchanged.
New install: follow docs/installation.en.md (back up both flash chips first).

New
Spanish interface: Options → Language now steps through English, 中文 and Espanol. The language row is
"Language" in every language, so it can always be found. Thanks to Pablo (@Pablog5395) for the translation.
(#13)
The caller's position on DMR receive: when the other radio sends its GPS position with the call (ETSI GPS
Info), the receive screen shows the distance and direction from ours (or its coordinates when ours is not known),
and so does Last heard. (#19)
APRS: "Send beacon now" in Options → APRS, and the beacon key is SK1 + 3 (it sends in any mode but Off).
The bottom bar shows @ while beaconing is on. (#18,
#22)
Fixed
Back from the VFO to the channel, the radio stayed on the VFO's frequency (no DMR, the S meter of the VFO)
until the channel was changed. (#20)
The quick menu and the channel details change things at once: the radio follows while the menu is open, and
the right key keeps the change (before, only the left key applied it).
(#20)
AM / SSB squelch no longer closes in every pause: it closes after the signal stayed under the level for
0.2 s (AM) or 0.5 s (USB / LSB). (#21)
APRS beacons go out with the APRS configurations of the 2025 CPS, a GPS position without a fix is no longer
used, and a beacon that cannot go out gives the error tone. (#18)
Key settings showed one action too few (the last one could not be changed).
(#18)
Known limits
P25: simplex group calls in clear only (no encryption, private calls, trunking or Phase 2); see docs/p25.md
No voice prompts; calibration is read only; no themes
"Safe Pwr-On" and "Sat (Manual / Auto)" have no effect yet
Not fully tested on the air yet: APRS decoding, the hotspot's CW ID, satellite passes, talkaround, distance sort,
the AM / SSB squelch hold, the caller's position
The Spanish interface has no accented letters (the fonts are ASCII)
