Description
Hello All,
I am trying to update my firmware for NodeMCU through OTA. I am using the basic HTTP_UPDATE example code given in arduino. The Bin File is placed on Github and trying to download that and upload it to the board.
Platform
- Hardware: [NodeMCU Amica]
- Core Version: [latest git hash or date]
- Development Env: [Arduino IDE]
- Operating System: [Windows]
Settings in IDE
- Module: [Generic ESP8266 Module]
- Flash Mode: [DOUT Compatible]
- Flash Size: [4MB/1MB]
- lwip Variant: [v1.4|v2 Lower Memory|Higher Bandwidth]
- Reset Method: [ck]
- Flash Frequency: [40Mhz]
- CPU Frequency: [80Mhz|160MHz]
- Upload Using: [OTA|SERIAL]
- Upload Speed: [115200|other] (serial upload only)
