The following example in C uses the REST interface with a secure SSL configuration to exchange AP configuration with the onboard ESP8266. The board is a Cactus Rev 2. The sketch updates the status every 60 seconds in the IoTLink dashboard. click on Learn More, then Examples, there are examples for Cactus rev 2 using…
The built-in esp8266 module of Cactus Micro need to upgrade firmware for support HTTP post request. There’s a little buggy for send NEWLINE to remote server. Upgrade the firmware for esp8266 Download firmware ai-thinker-0.9.5.2-9600.bin. Change the serial port to hardware serial. Use USB to UART converter to upgrade firmware. You can also refer this link…
We have tested to make Cactus Micro as ESP8266 programmer. It works very well. To do the work, you need make some jump wires. Steps for hacking For upload firmware to ESP8266, we need more stable connection for UART. So change the serial port to hardware serial port first. Add a jump wire ESP8266 GPIO0…
Cactus Micro communication with ESP8266 with SoftwareSerial port (RX: 11, TX: 12) default. We can change it to the hardware serial port Serial1. Prepare tools A knife A Solder Soldering the jumper Step1. Cut the jumper in the red square Step2. Soldering the jumper to other side You’re done. Now the Cactus Micro communicate with…
This is a simple demo using the ESP8266 and Cactus Micro (a arduino compatible board) to update a remote server (data.sparkfun.com) using a digital temperature sensor. Step 1: Materials The Cactus Micro is an arduino compatible dev board, it integrated a WIFI chip ESP8266. More information
