Arduino OTA for ESP8266

OTA may be done using

● Arduino IDE

● Web Browser

● HTTP Server○ This is the only NAT friendly approach, through periodic server polling

OTAXM

1. Port Wakaama (lwM2M) to ESP8266○ some coap enpoints○ attempt merging with ArduinoOTA (?)

2. Make it an Arduino Library○ enrich coap endpoints○ improve ArduinoOTA - Wakaama merge

3. Control ESP8266 from Leshan○ and Hawkbit in the future

Alternative approach: enrich Arduino microcoap with wakaama enpoints and modify ArduinoOTA to include lwM2M compatibility

Let’s share the glory (and the $$$)

Deadline 26 February
