/homie/config.json doesn't exist after using “ESP8266 Sketch Data Upload”

[Bee-Certain]

If I upload a configuration file with an error in the file, then Homie sees and reports the error. If I fix the error and re-upload, Homie says it can not find the file. (???)

Environment: Arduino 1.8.3, Ubuntu 16.04, homie-esp8266-develop, ESP8266FS-0.2.0

I have a config.json file with a deliberate error for ota.enabled:

  "ota": {
    "enabled": xx
  },

When I do a “ESP8266 Sketch Data Upload”, I get the following:

[SPIFFS] data   : /home/bob/Arduino/OGS_TH_SHT30_0.2.0/data
[SPIFFS] size   : 3052
[SPIFFS] page   : 256
[SPIFFS] block  : 8192
/homie/config.json
[SPIFFS] upload : /tmp/buildf16290c8068cf9b1e4282e095ac64b98.spiffs/OGS_TH_SHT30_0.2.0.spiffs.bin
[SPIFFS] address: 0x100000
[SPIFFS] reset  : nodemcu
[SPIFFS] port   : /dev/ttyUSB0
[SPIFFS] speed  : 921600

Uploading 3125248 bytes from /tmp/buildf16290c8068cf9b1e4282e095ac64b98.spiffs/OGS_TH_SHT30_0.2.0.spiffs.bin to flash at 0x00100000
................................................................................ [  2% ]

Etc.

After the upload completes, I enable the serial monitor and reset the Wemos D1 Mini and get the following: ✖ Config file is not valid, reason: ota.enabled is not a boolean Configuration invalid. Using CONFIG MODE 💡 Firmware bare-minimum (1.0.0) 🔌 Booting into config mode 🔌 Device ID is 5ccf7f2bb732 AP started as Homie-5ccf7f2bb732 with IP 192.168.123.1 Triggering Wi-Fi scan... ✔ Wi-Fi scan completed

So, clearly the file is being uploaded to the proper location and Homie sees the file.

So, I go in and fix the config file and re-upload:

[SPIFFS] data   : /home/bob/Arduino/OGS_TH_SHT30_0.2.0/data

And, after Reset:

✖ /homie/config.json doesn't exist Configuration invalid. Using CONFIG MODE 💡 Firmware bare-minimum (1.0.0) 🔌 Booting into config mode 🔌 Device ID is 5ccf7f2bb732 AP started as Homie-5ccf7f2bb732 with IP 192.168.123.1 Triggering Wi-Fi scan... ✔ Wi-Fi scan completed

Here is the config.json file:

{
  "name": "The kitchen light",
  "wifi": {
    "ssid": "be-green-demo-02",
    "password": null
  },
  "mqtt": {
    "host": "192.168.1.10",
    "port": 1883,
    "base_topic": "devices/",
    "auth": false
  },
  "ota": {
    "enabled": false
  },
  "settings": {
    "percentage": 55
  }
}

Never mind. I traded out the board for a new one and everything seems to be working.

It would be nice to understand what was going on and why I was getting the strange error messages.

By the way, thanks, Marvin for your excellent work.

Are you sure you had set the correct flash memory layout? The file uploaded to SPIFFS has a size of 3M??

If memory size of flashes is configured wrongly, it may happen that it is uploaded to wrong region? (See https://arduino-esp8266.readthedocs.io/en/latest/filesystem.html#flash-layout)

(I can't tell you where to set it in the arduino IDE, because I'm using platformio+Eclipse, there you can set it in the platformio.ini file with e.g. build_flags = -Wl,-Tesp8266.flash.1m64.ld

I have exactly the same issue with my ESP-01. Checked flash memory layout and it is correct. How can I fix this?

@ech89899 I have the same problem of config.json after burning Homie firmware build on top of EspEasy. The EspEasy was burnt on the ESP-12 before Homie. 2 boards with the same behavior.

I tried following:

• SPIFFS.format(); on boot.
• Remove /homie/config.json.
• Create empty /homie/config.json.
• Create /homie/config.json with all valid fields empty.
• Create /homie/config.json with valid values in valid fields.
• Full erase the Flash and redoing the above. No success so far.

As @Bee-Certain reported, burning the same firmware of Homie on new ESP-12 module works as charm. I think there are some residues of old firmware somewhere beside Flash...
