| That reminds me, in https://github.com/bshambaugh/BlinkyProject/blob/remoteSigner/edgeDevices/ESP32-testing/include/websocketserver_config.h I have the IP address of the laptop assigned by the router hardcoded which I can discover by hostname -I on the laptop. Recompiling the ESP32 with the new IP address when I move to a new network like 192.168.1.29 (or even if the router reassigns it .... occasionally locally I go from 10.0.0.4 to 10.0.0.5 and back again) is a pain. I think this is a different issue though....I just need to somehow give my devices unique identifiers, call out to them through some sort of broadcast scheme and pull down their assigned IP addresses. | |
| lots to think about, thanks for your help so far. (Find the IP address |

| I worked with this model during the EthDenver https://github.com/spro/char-rnn.pytorch . I did not manage to get the right shape for https://github.com/zkonduit/pyezkl/tree/main/examples/tutorial . (loading the model to convert to *.onnx) | |
| I learned a bit about ML though. :P | |
