please can anyone help me with fishball 7020 in particular usb Ethernet on android?

[tangradioxide]

i have been trying to get something working for a few months learning as i go but progress has stalled and it seems like nobody ever does what i am trying.
i have the fishball 7020 and latest tezuka running on sd. i did test the board on my linux desktop and rx worked. just to know the board is good.
i edited the virtual drive configuration file and got the sdr in ecm mode for android, and android shows 192.168.2.1 having several open ports. there is 5555 which i assume is adb bridge (correct me please if this is from the sdr), 8091, and one or sometimes two other random port numbers that are different each time i reboot the sdr.
my main problem is i dont know what i should be expecting to see here and how to take it further if it is all correct.
so far i only know 2 apps that should support pluto on android and they are sdrangel and sdr++.
both have no documentation relating to android or this use. sdr++ did have a forum post saying that the pluto ip was fixed to 192.168.2.1 which is why i reverted to that. neither software has connected to the sdr yet.
there are parts of the puzzle missing but i know i am so close to getting it working.
my end application is a light portable qo100 transceiver that i can go trekking with. i only need ssb, and bought specially a blackview rugged tablet that has enough battery to run the sdr for hours if not days.

so if anyone has any ideas, or could even plug a tezuka into an android device for a quick portscan or test you will be doing me a great service. anything will be useful to help diagnose what part of the system is needing adjustments. and what the ports im seeing are for.

the first photo is before i altered ip to 192.168.2.1 but still relevant

and ping test

i just did this full port scan including tcp and udp. theres a lot going on there.

I didn't try android plug for a while...I will do.
Question : your goal is QO100 rx only ? or RX/TX ?

[tangradioxide]

rxtx really but rx would be a start. i currently use rtlsdr for receiving and a ssb transceiver and transverter to transmit but locking uplink and downlink is terrible and drifts too much. its also too much gear to carry. my hope is to not just get rx and tx in a small box, but also lock my frequency in relation to the fixed frequency beacons on the satellite so a gpsdo is not needed. its a big list for santa Claus this Christmas. its very frustrating having all the hardware in front of me and not knowing how to make it work. but one day it will work and i can publish how-to for all the other mobile qo100 users.

[tangradioxide]

ok so i just got replies from both sdr++ and sdrangel. pluto is just a no. it doesn't work. so it looks like my tezuka firmware is probably running fine but i wont be able to enjoy it until someone writes an sdr app to turn audio to rf and vice versa. frankly i am really surprised that there is literally nothing available. powerful modern tablets and tiny wideband sdr at reasonable prices.....
oh well. maybe i will have to lash it up to my server as a websdr. in fact, could it do this by itself? is that the solution by having it run an html5 page that i can access from the browser?
im open to all suggestions, and if it just can't happen i will have to sulk a little and close this thread and thank people for the help thus far.

[tangradioxide]

no i didnt see anything there. what would that indicate? could my config.txt be wrong? i know theres supposed to be an analog devices splash webpage somewhere on the original version but i cant find it.
appreciate your help, season of goodwill indeed :)
ps. port scan doesn't show any open 8000

[F5OEO]

Have you tried on PC first to be sure ?

[tangradioxide]

ok its now plugged in the dell server. theres icecast server! theres no spectrum display but there is admin settings that i dont know login details for, and version, with some details. server status page has no information.
i notice that on this linux server the open ports are different from the android tablet

[F5OEO]

ssh to it with root/analog credentials

[tangradioxide]

sorry my bad. 8000 was in use by an internet radio server i used to use. i killed the program and now i get nothing on the sdr port 8000

[tangradioxide]

it seems all my network ports on localhost are getting redirected to the sdr ip address. strange. (all on 192.168.2.1)
my home network is 192.168.0. x

[F5OEO]

Your board delivering you a 192.168.2.10 address through ip over usb.
Seems you can now try on a browser http://192.168.2.1:8000

[tangradioxide]

again its redirecting to apache on the server. i need to get the sdr on a different subnet or something. i dont know why my 192.168.0.1 is getting redirected to 192.168.2.1. its only when the sdr is attached that xx.2.1 exists

[tangradioxide]

i don't see reason for it here

[tangradioxide]

im only on usb btw

[tangradioxide]

damn server has a virtual bridge i forgot about. i cant change that. im have to drag out an old laptop and start again. im dumb as a bag of spanners

[tangradioxide]

so i decided to start with a clean system. installed the latest debian xfce on a laptop, plugged in the sdr and network wont connect to it at all. i get the usb drive but thats all.

is there a way to reset the persistent settings (virtual usb with config.txt) and i will start again.

i can still get an ip on the server and tablet, but only a 10. xxx local ip on the fresh debian install.
bad to worse

[tangradioxide]

i also got this suggestion elsewhere

could it be possible to run the sdr software on the sdr hardware as its already running linux,

Possibly. Try compiling the server version of SDRangel - and then run Remote TCP Sink plugin.

and control it from android like you would a websdr?

Yep. You can use Remote TCP Device in SDRangel to connect to a remote device.
