Solo mining in 2021 - Lottery ticket style

[talvasconcelos]

So, I want to fire up my Antminers for lottery ticket style solo mining, on a RPI!

Thing is, I don't want to have another full node for this. I have a full, unpruned node (latest 0.22.0) already running on the LAN, I wanted to use that to connect to and just run BFGminer (I'm actually trying cgminer now) on a RPI on the same network.

What are my options? @luke-jr ?

Should "just work"

[talvasconcelos]

--generate-to bc1xxxxxxxxxx spits out invalid address!! if i don't set a generate-to address and I get REALLY lucky and find a block, where would the reward go? the remote/lan bitcoin core i'm using for mining?

Yes, Bech32 isn't supported yet. Just use a legacy/Base58 address.

I suspected that, but something else is wrong. Bfgminer doesn't seem to connect to my node on the lan (cgminer does but doesn't do GBT), and also, even if I try to connect to a pool just to see if things work, the pi can't find the miners.

Sorry for keep coming back to this... I have a couple, just want to use 1 actually, antminers U1 and U2 Just installed raspberry pi os, downloaded bfgminer 5.5.0, i can connect to my LAN node, etc... only problem is that th RPI doesn't even recognize the USB miners, bfgminer doesn't find them, so no hashes.

lsusb doesn't get them sudo ls /dev/*USB* returns nothing! the chip on these things is BM 1380 U020114E2, mayve the pi doesn't have the drivers! I'll try tomorrow on a windows machine, just to rule out the chance that the miners are dead... they do get hot as hell though!

Can I get any help on how to have raspian recognize the miners?

You probably need a USB driver installed. Try ftdi_sio, cp210x, pl2303

After modprobing those and running bfgminer with -D -T --verbose outputs this:
