Hi.
I bought a few LK3s before (I have about 10 of them) but of the latter I acquired, 1 has a weird issue.
1. Full reset (device resets, DHCP enabled)
2. Detect device from DHCP lease, login
3. Set 1-wire to BME280 (confirm it works, T, H, P work as expected)
4. Go to Network tab and set the network: change host name, set IP to manual, DNS, gateway.
5. The device resets (automatically when changing IP)
6. Connect to the device via new IP, log in, everything works but WILL NOT READ THE BME ( reads --- as if it's not there)
Any ideas, before I RMA it? It sounds like a flash memory bug? I have tried to reflash the firmware, brought up to latest 1.43e (I could try 1.44) but throughout the updates and resets it keeps behaving like this.
I tried:
- Putting the BME in another device (works fine)
- Putting another BME in this one (still won't read)
- Resetting the device (won't read)
- Loading defaults (won't read)
- Trying to see if it reads DS18B20 (won't enumerate DS if BME isn't working)
- Swapped power from wall wart to PoE and tried the wall wart on another LK (works as expected)
Once the bug triggers it won't read anything over 1-wire until reset by keeping the reset down in which case it will read until IP is pinned to manual.
Do I just return it? I don't want an unstable device.
