Trying to connect RNSD/Nomadnet to RNode in Termux

[stickyvalentine]

I'd like to use RNS and Nomadnet in Termux with an RNode if possible using a Galaxy S23+, not rooted. I’ve installed RNS and Nomadnet in Termux and both are working, but I’m not able to get Reticulum to connect to an RNode (Heltec V3). I’d be happy to connect over USB but bluetooth would be even better. I have Sideband installed and it can connect to the RNode through both USB and BLE, just for context.

I’ve seen people mention that they have Nomadnet working on Android with Termux, and I assumed they have been able to get it connected directly to an RNode device, which may or may not be the case.

Here is what I’ve tried:
Installed termux-api

$ termux-usb -l
[/dev/bus/usb/002/002]

$ termux-usb -r /dev/bus/usb/002/002
“Allow Termux to access CP2102 USB to UART Bridge Controller?” > OK
Access granted.

Set Reticulum RNode interface with port = /dev/bus/usb/002/002

$ rnsd
[Critical] Could not load jnius API wrapper for Android, RNode interface can not be created.
[Critical] This probably means you are trying to use an USB-based interface from within Termux or similar.
[Critical] This is currently not possible, due to this environment limiting access to the native Android APIs.

Also:

$ termux-usb -r /dev/bus/usb/002/002
“Allow Termux to access CP2102 USB to UART Bridge Controller?” > OK
Access granted.

$ termux-usb -e rnsd /dev/bus/usb/002/002
Access denied.

The message obviously says that it isn’t possible, but I’m wondering if people have found some way to make it work or is it really just not possible at this point. I’m afraid I’m missing something obvious and others have made this work somehow. If anyone can help or let me know that this really isn’t possible, I’d appreciate it.

I spent probably more time than I should have trying different ways to get around this limitation but from what I can tell there really isn't an easy workaround atm, at least not without without a rooted device. I guess it should have been obvious, but I kept finding leads that seemed promising. I don't know if it's helpful to anyone else, but I thought I'd leave a follow up.

Termux doesn't have full acess to the native Android APIs for USB and Bluetooth.

You can use Sideband to host a system-wide RNS daemon on Android, which can access USB and Bluetooth devices, and also can keep the WiFi card alive, etc.

Just copy the RPC key from Sideband into the Reticulum config in Termux, and it will all work fine.

Thank you! I never would have thought of that!

Totally worked! I really appreciate it
