ESP-01 ? #3

Closed MoonMoon82 closed 4 years ago

MoonMoon82 commented 5 years ago

Hi! I'm using a ESP-01 board with a slightly modified usb-serial adapter like https://www.amazon.de/AZDelivery-ESP8266-ESP-01-USB-Adapter-Arduino/dp/B078J7LDLY to upload sketches.

So usually I upload a new firmware by serial connection to a ESP-01 board. After I had some really good experiences with WebOTA on Wemos D1 boards, I also wanted to give it a try on a ESP-01 board. So I made this basic sketch:

`

include

include

include

include

include

void setup() { delay(2000); pinMode(LED_BUILTIN, OUTPUT); WiFi.mode(WIFI_STA); WiFi.begin("", ""); //insert your wifi credentials while (WiFi.status() != WL_CONNECTED) { digitalWrite(LED_BUILTIN, HIGH); delay(100); digitalWrite(LED_BUILTIN, LOW); delay(100); } webota.init(8888, "/update"); }

void loop() { digitalWrite(LED_BUILTIN, HIGH); webota.handle(); delay(500); digitalWrite(LED_BUILTIN, LOW); webota.handle(); delay(500); } `

Now I can access the webOTA interface on :8888/update and upload a new "firmware.bin" . Right after reaching 100% nothing happens anymore. I have to update by the serial interface to make the ESP-01 work again.

I watched the build output for the serial interface saying it's uploading a compressed file:

`Looking for upload port... Auto-detected: COM7 Uploading .pioenvs\esp01_1m\firmware.bin esptool.py v2.6 Serial port COM7 Connecting.... Chip is ESP8266EX

Could it be I have to upload a compressed firmware.bin ? I'm really sorry for beeing such a noob :( Do you have a hint for me?

Kind regards MM82

It's because the ESP-01 has not enough flash memory isn't it?

scottchiefbaker commented 5 years ago

This library only supports the ESP32 and ESP8266.

MoonMoon82 commented 5 years ago

The ESP-01 is a ESP8266 board. It has 4Mbit flash on it. This isn't enough for a OTA update?

Did you ever figure this out?

Closing this due to lack of response. If it's still an issue let me know.
