Can't find my Red Pitayas on the Network (2024)

#2814

Are you trying to access two RPs from the same computer? If so, you have to rename the DLL so that each one is accessed independently, and use two separate SkimSrv directories (SkimSrv and SkimSrv2), one per Hermes DLL.

Let's say the two RPs have MAC addresses ending in 1111 and 2222. You must rename HermesIntf.dll to

SkimSrv\

HermesIntf_1111.dll

SkimSrv2\

HermesIntf_2222.dll

Of course everything has to be on the same subnet (same first 3 parts of IP address). So, if your Windows PC is using WiFi and is on 192.168.1.1., but your Router puts Ethernet devices like the RPs on a different subnet, like 192.168.0.1, then they won't be able to find each other.

Hi!

Soon I will be really "crazy" if I do not find a solution how to find my Red Pitay's on the local network!

I have find one of them but not the other RP. I do not know how I find it!

Hermes Lite 2 and other Ethernet devices are found very easy by the router but not the Red Pitay's.

Sometimes I can see them in Ethernet device list but without IP number and sometimes not!

I am not the best man regarding network technology but I understand the basic and little more!

I have had a working setup with both RP1 and RP2 working since month back.

But I starting changing things.

Well, perhaps you can try to change things back to the way they were before?

Well, well, remembering things is not my strong thing! Ask my wife!

Starting using new SparkSDR for Red Pitaya on my RP2 and on my RP1 CW Skimmer and RTTY Skimmer. Working great!

Why SparkSDR? What's the advantage? Are you using a Beta version? Did you try to power cycle the Red Pitayas so they could obtain a new IP address from your Router via DHCP?

SparkSDR is a great multifunctional program. If you want to save system resources and have FT8, JT9/65, PSK 31/63, WSPR, running at the same time . I have used it since a year back on my Hermes Lite 2 which in itself is a great receiver/tranceiver. Now is SparkSDR 2 on market, also for Red Pitaya, in a release candidate version. Quickly developing.

Now working with SparkSDR, CW Skimmer and RTTY on RP2 and RP1 could not be found!

I assume you mean CW Skimmer Server, not CW Skimmer.

Correction: Now working with SparkSDR, Skimmer Server and RTTY Skimmer Server on RP2 and RP1 could not be found!

I have renamed in my SkimSrv folder my HermesIntf.dll to Hermesintf_61a2.dll which is my RP2 and also my content in CWSL_Tee.cfg to HermesIntf_61a2 64.

If you are starting the Skimmer with the Aggregator, you must also update CWSL_Tee.cfg in the Aggregator's folder.

I do not start it with the Aggregator. I start it directly in SkimSrv folder.

Is there any other files to be changed with to 61a2?

See above.

The other RP1 has 5db6, the one not found by router.

One is found, one is not?

Yes my 61a2 is ok the other one is not.

But I suspect that maybe my RP1 has in someway changed sub net. Any tool/method to check that up?

Yes. Connect a USB cable to the secondmicroUSB port on the Red Pitaya (not the one used to provide power, but the one next to it). This will be recognized by Windows as an FTDI virtual serial port. If necessary, use the Windows Device Manager to determine the new serial port number.

Next use a terminal program like PuTTY to connect to create a new SERIAL connection to the new COM port, using 115200 baud, N, 8, 1. This will give you a Unix command prompt. The command ip addresswill show you something like this (if using the Ubuntu Linux distribution):

root@rp-f05272:~# ip address

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

3: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default

Or it will look slightly different if using Pavel's Alpine Linux image:

rp-f050eb:~# ip address

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

One of the inet addresses should be on the same subnet as your Router.

I will look at this when I am in contact with RP1. Just now only U-Boot 2018.01 (Oct 20 2018 - 19:53:32 +0000) Model: Red Pitaya Board Board: Xilinx Zynq loading. Seems that I missing something! Where is the image!

Closer look showed a problem with SD Card. No contact. Formated a new card and copied image to the card. Now I had a functional RP1 again.

I have tried to use static IP address but there where no success with that. Now just DHCP running to find IP addresses for my devices

Whatever you changed in Linux to assign it a static IP address probably messed up its ability to request an IP address via DHCP. You can reboot the system while connected via the serial port to see any error messages at boot time regarding obtaining an IP address from your Router.

My big problem is to see both my RP’s in Ethernet Device List in Router with IP addresses!

That will only work if your RP is properly requesting an IP address via DHCP, and getting one.

Oh, so you are only running one app. at a time?

Using CWSL_Tee, we can run CW Skimmer Server and RTTY Skimmer Server and multiple instances of HDSDRsimultaneously, all sharingthe same 8 band receiver stream from one RP.

So, is there any way to use CWSL_Tee or ExtIO_CWSL with SparkSDR?

#2824

Hi!

On my HL2(12 fq) and RP1(16 fq), all applications, in total 28 fq running at the same time.

RP2 running FT8(8 fq) at the same time.

#2825

OK, so where is the documentation that shows how to run both CW Skimmer Server and RTTY Skimmer Server and SparkSDR one RP, on 8 different bands, without using CWSL_Tee? Pavel's documentation does not explain it.

#2826

I still do not understand your claims Sven.

To be clear, I'm asking if you are somehow making all of these programs (RTTY Skimmer Server, CW Skimmer Server, and SparkSDR) share the same RP at the same time. I know you can run one program at a time on different SDRs, but that's not the question.
