What MMDVM_HS board do you have?

[hoky]

@juribeparada It shows "JumboSpot"

[IS0FFD]

to upgrade firmware via ssh use

cd ~

curl -OL https://raw.github.com/juribeparada/MMDVM_HS/master/scripts/install_fw_hshat.sh

make the script executable: chmod +x install_fw_hshat.sh

stop your MMDVMHost process and run (you will need the root password): ./install_fw_hshat.sh

and wait to complete the upgrading process.

[hoky]

got the same error。

I google the hotspot and maybe it's the reason.

I will try.

[juribeparada]

Exactly, that board doesn’t have the proper GPIO lines connected, then you have to enter to serial bootloader manually.

[hoky]

Is there howto documenta exist？Need special equipment, cable?

[IS0FFD]

@hoky my MMDVM_HS_HAT "clone" have the full GPIO socket...

why in your board don't have the SMA socket or an integrated antenna?

[juribeparada]

@hoky, you have to understand I can’t support all the hardware that are based on this firmware, specially clones of well known boards. The board manufacturer should provide that support, specially if there are differences from my original design. If you can’t find that information, you could read BUILD.md for detailed information of the original MMDVM_HS project.

[rogerclarkmelbourne]

@hoky

The board could be DOA.

You could try posting to www.stm32duino.com as this repo uses my core Arduino code, and www.stm32duino.com is the community for that core (and some other Arduino cores)

With the generic STM32 boards, people on the forum often find they have not been tested at all by the manufacturer and there are soldering faults etc, which prevent the board from working. And even if the code uploads, it may not run if the crystal is faulty

[hoky]

Thank you @rogerclarkmelbourne @juribeparada I have two hotspot, i will try one for test.

[rogerclarkmelbourne]

@juribeparada

FYI. I've been trying to track down who makes these clones and what they consist of.

From my research so far,

It seems to be this

They seem to be a modified version of this board

e.g. sold here

The HS8JCV is supposed to be a VHF not UHF version, but these are being sold as both VHF and UHF

But whether thats possible I don't know

(The original master of all of these is https://github.com/mathisschmieder/MMDVM_HS_Hat)

Do you know if there are sources for the version with the OLED display , as I cant find a fork of this board which has a display

Edit.

Looks like the display is based on the information in this blog

https://www.f5uii.net/en/installation-oled-display-ssd1306-raspberry-pi-mmdvm-mmdvmhost/

However its unclear how the OLED is connected to the correct pins.

I cant see how the RPI header matches this OLED display directly.

Hi Roger,

Yes, somebody took the Mathis design of the MMDVM_HS (MMDVM_HS_Hat) and they did a copy and began to sell. Some of those board are exactly similar with the original design, and other ones have the name JumboSpot, but they are MMDVM_HS_Hat or maybe ZUMspot copies. The worse thing some of them didn’t put the full header connector, or there are problems with the component selection for the antenna matching network. With a external 18 nH in L1 and L2 terminals of ADF7021, you will have VHF support (with UHF also). But generally you put your antenna matching/filter network for one band (UHF), and then VHF operation is not so good, but is ok for short distances.

I don’t know the sources for the version with OLED display.

Regards, Andy.

Hi Andy

Thanks.,

The VHF version is a fork

https://github.com/HS8JCV/MMDVM_HS_Hat

But I don't know if that fork is VHF only or would also work with UHF.

I think you are saying that its designed for VHF but works on UHF with shorter range.

[juribeparada]

I think those board will do VHF and UHF, but probably UHF with limited output power and a reduced RX performance due to the different filter+matching net. The only way is using two different group of filters and selected by RF switches, but that increasing the final price of the board.

Regards, Andy.
