Baofeng DM-32 --> OpenDM-32

Observations:

DMR doesn't work.  No RX or TX.

No way to select AM mode for VHF aircraft band receive.

Make sure the frequency, Color Code (CC), and Time Slot (TS) match on both sides. DMR should then work as expected.

BTW, I've added AM and SSB (USB/LSB) support to the latest code, but I haven't released a firmware build yet. You can build it yourself from the source code.

When I upgraded to this firmware, my existing codeplug remained untouched. 

All the DMR settings were correct, they worked with the previous firmware. 

I did make a new test codeplug, and the same result.  Green light comes on during a transmission, but no audio.  FM analog seems to work fine.

Is there a "promiscuous" mode?

Maybe some corrupted codeplug data is causing the firmware to behave abnormally.

When you press the PTT button, does the screen switch to the TX interface or display any error message? The LED should turn red during transmission.

When I press the PTT on a DMR channel, the top LED flashed red rapidly.  No error messages.

The LED should stay solid red while transmitting. If your 16 MB flash doesn't contain any sensitive information, could you share a backup with me? I think we may only need the first 2 MB to start troubleshooting. You can compress the backup into a ZIP file, which should make it fairly small.

Hi,

Thanks for sending the flash dump. I loaded your codeplug and settings onto my own DM-32, keeping my own calibration for now. On both VFOs, FM and DMR, my radio receives and transmits normally with your data. So the codeplug and settings don't seem to be the cause.

A couple of things are worth checking on your side:

RX Only: some of your channels are set to RX Only, and PTT is refused on them.
VFO split: one of your VFOs has different RX and TX frequencies. It transmits on the TX frequency, so a radio listening on the RX frequency won't hear it.
Could you let me know:

Which channel or VFO you're on when it doesn't transmit.
What the screen shows when you press PTT: a message, the TX screen, or nothing.
Whether another radio nearby hears anything.
Whether it transmitted fine on the stock firmware.
I'm now testing with your calibration data as well, and will post the result.

Stock firmware everything was okay.

I am more concerned right now, that it doesn't receive anything on DMR on any DMR channel, in channel mode or VFO mode.  It worked on the stock firmware. 

I have other radios that can receive the DMR transmissions with no issue, but this firmware, there is no audio and no S-meter movement.  I can understand that one channel might have incorrect settings, but not on every DMR channel.  I have entered the information in VFO mode with the color code, slot, etc., and nothing.

Maybe there is a way to completely wipe the firmware and start over again?  Also, I find that I can use OpenGD77 cps to flash the .bin file with its built-in flash utility.

First, make sure FM mode is working properly. Then, tune to the DMR frequency, switch to FM mode, and set the squelch to 0. Check whether you can hear the digital signal in FM mode.

If you hear nothing, it likely means there is no signal on that frequency. If you can hear the digital signal, switch back to DMR mode and see whether the radio can decode it.

If you have another DMR radio available, it would be much easier to troubleshoot and identify the root cause of the issue.

The DMR is working
I believe the S-meter readings are incorrect 
Version 0.1.0

For me, DMR only works on Color Code 1. Even if I change the setting on the display, the radio remains locked to CC1; in reality, it only transmits and receives on CC1 and does not pick up any other color codes. Thanks for your efforts.

Also, the new AM mode for the air band works very well. Thanks again.

Version 0.2.0 fixes the S-meter and Color Code (CC) issues, adds AM/SSB demodulation modes, and includes several other bug fixes and improvements.

Thanks! I also noticed that the battery indicator always shows a full charge. It’s possible that the ADC isn’t reading the values ​​correctly, or that the wrong channel has been selected.
