hblink-org / hblink3 Goto Github PK

Hello,
It’s possible to implement the ovcm bit inside the code ?

like mmdvm?
I used the openspot and there is not possible.

maybe it’s possible only the OVCM to the hotspot

thx

Hi,

I am using hblink in a bridged configuration and have noticed DMRA frames cause an exception in the logs:

Looking at the code, _rf_src is indeed referenced before assignment. A quick fix would be to just pass DMRA frames but it would be nice to extract the info I guess.

Thanks

Sometme after commit 08f6669, XLX support has vanished. Confirmed locally by a hard reset and XLX support is there.

There's a need for int.from_bytes() here, but we should look at the entirety of the code to make sure we're not just throwing duct tape on the problem.

@randybuildsthings said in an HBlink message thread:

"We're using socket.gethostbyname() which only supports IPv4. We'll have to change that."

For context see https://dvswitch.groups.io/g/HBlink/topic/81430483

As discussed on the groups.io mailing list and submitted with some additional data.

At the end of any transmission to a bridge group in which an XLXPEER participates, HBlink thinks the XLX is sending a brief new group call in response to the end of the original stream. I am fairly certain (through packet capture) that there are no out of sequence packets being sent back from the XLX.

HBlink is somehow confused by what it thinks it sees. This results in artifacts of a new transmission in the log when none was went. It gets in the way of private calls working properly, as calls get forwarded to the XLX (where the desired recpient is not).

Configs and other data follow:

Recently， BM servers bring TOTP/AirSecurity service online，（Different Ids）users need to dial TOTP codes to confirm their identity by private call before group calling。It seems hblink3 won’t transmit the private call with TOTP codes to BM servers when local repeater is bridged to BM servers。Are there any plans to adapt to this function in the near future？
