After I finished roasting and cooling the roaster today, I thought I’d upgrade the firmware. When I tried to apply the update, I immediately got an error message that the bullet wasn’t connected. The display on the bullet at this point showed PH and the fan was on high at this point. I unplugged the USB cable, restarted the software, etc. without success (even though RoastTime would detect when the USB cable was plugged in), Finally, I unplugged the roaster and plugged it back in. The fan came on but the display remained black. Tried it a few more time including after waiting several long minutes. Same thing.
Any idea what is going on?
ps: A couple of things that I have been happening on the roaster lately. May be unrelated. But I thought I’d mention it in case it isn’t.
For the past several roast sessions, the roaster display would sometimes go crazy (numbers changing all over the place, beeps, etc.) immediately after I charge the beans. Whenever this happened, I’d immediately drop the beans and restart the roast.
Also, today I noticed that the light would sometimes go out when I moved it. The issue seemed to be either at the USB connector or at the cable near the connector. I haven’t tested the lamp on a different USB connector yet.
