hermes lite 2 netzwerk

[Oliver Kudalski]

i bought a HL2 bord and i only have problems

i cannot establish a network connection to the bord

the two led on the left side are flashing and the two led

on the right side are constantly lit.

i also do not see an ip or mac adress from the bord

i Say the bord is defect??? or???

i have only run it on a switch and a pc nothing works

is it defect?????

Hi, Oliver.

https://github.com/softerhardware/Hermes-Lite2/wiki/External-Connections explains the LEDs.

This is what they mean in your case:

D2 Flashing: H2 is idle and is seeing a valid Ethernet clock.

D3 Flashing:  HL2 IP address assignment succeeded via fixed IP or APIPA which is attempted if DCHP fails in the first 15 seconds after powerup

D4 Lit: 1000 Mbps Ethernet link is established

D5 Lit: Radio subsystem (AD9866 device) is operational

So,  the Ethernet is working and the radio device is working, it is not defective.

You need to review your DHCP server to see if it is providing an address.

If it does not provide one in 15 seconds it will use the APIPA process.

https://wiki.wireshark.org/APIPA is a good reference for how this works.

Apparently HL2 always tries 169.254.19.221 first, according to earlier e-mail.

So, if you connect direct to PC, try using a fixed address like 169.254.1.1 with netmask 255.255.0.0 and then ping 169.254.19.221.

Or search this email group for APIPA, it will give you some things to try.

Let us know how it goes...

Regards,

RDP

Hi Oliver,

I do not think your HL2 is defective. I think you need to review how your are connecting your HL2 to a PC or home network. Just like the smart TV, phones, tablets, computers and Google Homes in many homes, your HL2 is a network appliance and must be assigned a valid IP address. There are 3 ways to do this:

1. Connect your HL2 to a home network with a DHCP server. Most home networks have a DHCP server as that is how any device typically connects. This is the recommended method. This is how I use a HL2 in my home.
2. Assign a fixed address to your HL2. First, you must connect with a known good method, usually DHCP. Then you can use Quisk, SparkSDR or the hermeslite.py to program to assign a fixed IP to your HL2. Then after it is power cycled, it will respond to that IP. The computer it is intended to communicate with must also have a valid IP address typically in the same subnet. This is how I have setup my remote station with a single PC and HL2 connected directly.
3. Use the APIPA address. If the HL2 doesn't get a valid address via DHCP and doesn't have a fixed IP, then it will default to the APIPA address of 169.254.19.221 assuming the MAC address is the factory default. This works best with Windows. You still need a host computer that is configured to connect on that subnet, just as RDP describes. Some people say this method works well, others can have issues with certain operating systems or SDR programs. I recommend if you use this method to always power cycle your HL2 if you are changing software.

73,

When you have over 40 devices on your home network with half of them not showing a hostname, the HL2 is practically impossible to find.  It takes the IP of existing devices and will not show it's MAC address.  I had it running once I found the IP once.  Without powering it off at all, it no longer has the IP it had.  What a struggle to get connected to it.

[Alan Hopper]

Hi Scott,

In normal use you should not have to find the ip, the sdr software should do that for you using the discovery process. Are you trying to do something out of the ordinary? The network troubleshooting section in the wiki might have some useful info.

Hi Alan,

I am using a Google Nest router which works great for everything I have here.  The HL2 is connected to it via Ethernet and just now when I powered it on, it wants to use the last IP it had, but did not power on and I can not ping it.  Yesterday when I first connected it, I powered it off a few times.  Each time powering back up it chose a different IP address.

Okay, it is now keeping the last IP, but I've found that you have immediately power it on with Thetis when the HL2 boots up.  Leaving the HL2 powered on with Thetis off, the IP gets lost.  If I've found the right combination to get it connected, then I can deal with that.

[Scott Gibson]

Another thing that is weird is, the setup for Thetis now shows a different MAC address for the HL2 than when I do arp -a at a command prompt.  Same IP with two different MAC addresses.  I don't think there's a conflict since I cannot ping the IP when the HL2 is off.  My guess is that it is my router though and will try restarting it.

[Scott Gibson]

Still happening.  Without turning the HL2 off, I flushed my DNS and restarted my PC.  Then tried pinging the HL2 with no reply.  I turned off the HL2 and turned it back on, then opened Thetis.  Thetis found the radio, then pings started replying.  I then did the command to show the MAC address and Thetis shows a different MAC than my router.  If I just do arp -a to show all MAC addresses on my network, I never see that MAC shown in Thetis.

Anyway, the work around is turn it off and on again.  Weird though.

I don't use Thetis, but personally I always fix the IP address of the HL2 using IP Reservation in my router.

Here are instructions to do that in the Nest router. Then it will always come up with your known reserved IP. I would say that solves a lot of your issues?

Thanks Max.  I did reserve the IP for the MAC that shows on my router.  The MAC that shows in Thetis is a mystery.  

[Mike Lewis]

The MAC showing in Thetis is corrupted.  It has the same correct last 4 bytes of your HL2 placed as the first 4 with 2 random bytes at the end.  You might back up your Thetis database and reset it, that is a garbage MAC address stored.

I was running Thetis 2.08 and HL2 2.9.0.8 Beta 5 versions OK.  I just installed Thetis 2.10.1.x64.msi and at the same time the Thetis 2.9.0.8-HL2 Beta 6.  It discovers and operates my HL2 fine but setup shows the bytes incorrectly, just like reported below.  Given the HL2 is confirmed to be the correct MAC (others including Thetis can operate it) I might guess the setup screen MAC displayed is a display/interpretation bug and seems to not affect anything.

 

 

Reset the database did not fix it.

Here is PiHPSDR discovering the correct IP and MAC.

 

SparkSDR also works fine.  

 

I then started up Thetis 2.10 and it raised a dialog that it would merge the old database found from 2.08.  It then said succeeded on app restart.   It displays the same incorrect MAC address but still finds the HL2 OK.   It displayed wrong before and after the DB imports and resets.

 

I would conclude that the problem is display UI in Thetis 2.10 and can be ignored.  

 

Here is my Thetis HL2 Beta6 network setup section.  I have 2 HL2s and have reserved DHCP address for each MAC after changing the 2^nd unit MAC address.  You can try static/select IP.

Hi all, regarding the HL2 MAC address displayed in Tehtis, this has shown "in the wrong order" for as long as have been a Thetis user. 

C0-A2-13-DD-49-06 shown in Thetis is really  C0-A2--49-06-13-DD

And for another example,  if you set a HL2 custom MAC of C0-A2--49-06-12-34, it will display in Thetis as C0-A2-12-34-49-06. 

I don't know why this happens, but it was something I noticed a while back. I can't remember if I reported this issue on the group or not... 

@Scott - Either way, your database is probably not corrupted.

[Mike Lewis]

Looking deeper my HL2 is 00-1C-C0-A2-13-DD (and the 2^nd unit I assigned to 1 higher at :DE).

SDR Console reports this correctly.  Thetis has C0-A2-13-DE-49-06.  The 49-06 would go to the 1st 2 bytes, but is not just out of order, the values are also wrong.

The arp mac is the same as I have on my HL2 on my network. My beta5 Thetis shows no mac listing – blank. All HL2s have the same mac address.
