The default firmware for esp8266 is espduino not AT firmware. The espduino firmware is easier to use for REST http request. Some examples available [here](http://wiki.aprbrother.com/wiki/Cactus_Micro_R2_Tutorial#For_espduino_library_from_Tuan_PM). If you’d like use previous AT firmware, you can re-flash the firmware yourself. - The [AT firmware](http://abcdn1.qiniudn.com/ai-thinker-0.9.5.2-9600.bin?attname=) - [How to made Cactus Micro R2 as ESP8266 programmer](http://wiki.aprbrother.com/wiki/How_to_made_Cactus_Micro_R2_as_ESP8266_programmer) ---

I wasn’t using AT, I followed the Tuan PM guides. The buad rate for Serial1 was different, but I figured it out - 115200. However, I’m getting “ets Jan 8 2013,rst cause:1, boot mode:(3,7)” and no further functionality from the ESP8266. ---
