Cannot Flash Firmware

[umtauscher]

Hi Pascal,

I purched your great device in July. Since I haven't had the time to install it up to now, I tried yesterday.

Unfortunately this thing doesn't connect to my bambulab printer, so I tried to flash the firmware. So I tried conneting with USB on my iMac but the flash routine states, "Your ESP8266 board is not supported". Could you please help me how to flash the latest firmware onto this?

[madnotna]

The ESP8266 is outdated as Bambu Lab changed the MQTT. From that moment the ESP8266 is not responding to the MQTT due to insufficient memory of the chip.

@umtauscher I was able to install a version from the experimental page on my ESP8266. I haven't tested it yet though, waiting on LEDs...

[umtauscher]

nope - doesn't work. Flashing works though, just not the normal operation.

[AnalyticETH]

Where do you get stuck? I've set up the connection but I get MQTT errors, i guess our ESP8266s cannot handle the newer and presumably more complex MQTT

MQTT CONNECT_FAILED
Updating leds
Printer offline, Turning Leds off
MQTT CONNECT_FAILED
....(loops)....

[umtauscher]

The LEDs just are erratic.

I just got myself an ESP32 version and I can see how the LED's should behave. BTW you have to enter the serial number of your printer (topic) in the english UI it's refenced as "device info".

I just connected via usb again: The log states "failed to grow buffer" and then the firmware crashes.

I think it should be able to handle it, thats really not much data. I am not sure what the limitation here is

BTW you have to enter the serial number of your printer (topic) in the english UI it's refenced as "device info".

I dont seem to be able to access any UI on the device's IP. I can update config using this though: https://www.dutchdevelop.com/blled-configuration-setup

I was able to get a little further after reflashing and resetting configs. Now I get this error below, which it looks like is issue #19

Seems like it might be working actually, regardless of that error? It knows its printing right now per the first few logs. I'm still waiting on my LED strip so my testing capabilities are somewhat limited at the moment. More wanted to see if I need to order another ESP32 or not....

BTW you have to enter the serial number of your printer (topic) in the english UI it's refenced as "device info".

What I meant was the UI on the display of the printer.
