It didn’t mention anything about the CPU in the install instructions…
Try locating the binary that crashes with the "Bad CPU type" exception and run the file command on it. It will show you which architecture the binary was built for.
I couldn't find anything on that yet. I think that since the project is still in a rather early stage of development, it's more of a proof of concept. But I do know that the PCAPs are saved on the device, and you can download them onto another computer.
Is it necessary to get a cell plan to run the hotspot?
As far as I'm aware: no.
Cell-site simulators could theoretically only target devices that connect with a valid IMSI, but I kinda doubt that they are doing that. But you could get a cheap prepaid SIM, instead of an actual cell plan.
This is the easiest explanation I could come up with:
Your phone (or other cellular devices) constantly broadcasts a few identifiers. The IMEI, which is tied directly to the cellular hardware in your device, and the IMSI, which is tied to your SIM card. Law enforcement uses so called cell-site simulators, which basically pretend to be cellular antennas, while actually just grabbing IMEIs and IMSIs from every device in the area. This is often used during protests, in order to identify those who attend them.
Rayhunter is a piece of software that detects the presence of cell-site simulators, making attendants of protests aware of the hidden danger.
This is especially important, now that the US basically transformed into an authoritarian state. We've already seen how Trump strategically uses law enforcement to crack down on protests, such as the BLM movement in 2020. (https://www.youtube.com/watch?v=K_a63r5Km9I) Being aware of law enforcement/intelligence operations that try to identify and track down protest attendants is more important than ever.
If they're more sophisticated, they have lists of VPN server IPs, and compare every user's IP against those lists
There's an even simpler way: Just look up the ASN of the IP's associated ISP, and block it, if it matches the ASN of a datacenter ISP
Proton VPN offers special VPN servers for streaming, they can circumvent the second type of blocking by using residential IP address ranges, but not the first one. But they generally have pretty good IP reputation (at least on their paid servers, free is a whole different story, but I don't think they even give a fuck), because they're pretty good at anti-abuse.
The best solution IMO are seedboxes
We also have a community dedicated to them: !seedboxes@lemmy.dbzer0.com
