What I need: I need a LoRa concentrator, without going through TTN. I need to process received raw data in the RPi
What I have: I have a RAK7244 with the LTE module, running Chirpstack and HTTP Integration.
Regulatory Domain: USA.
What it is and is not doing: It boots up, the GPS displays my location on a surprisingly accurate map, ifconfig shows the browser interface, the wireless client, and the loopback interface. the presence of the map indicates I have internet connectivity
It appears to me that I need tcpdump to access the packets on the loopback. I can’t get tcpdump. when I try it jumps through the usual hoops, then fails when it can’t find the package. I tried
apt install tcpdump on the RPi I use to interface with the 7244, and it installed immediately.
I have internet connectivity on both devices, another similar device on the same network loads the apparently necessary program, so it appears that the OS is lacking some necessary bit of software to retrieve packages.
How do I obtain tcpdump without apt? how do I install apt without apt? Am I missing something simple?
