Need help with /dev/ttyMFD2
If you want to use WiFi or Bluetooth, I suggest you to check the following documents:
For Bluetooth you can use the Intel® Edison - Bluetooth* Guide. An alternative could be using an SPP interface to send and receive data. Also, take a look at this file: How to run SPP-loopback.py on Edison
For WiFi; you can use WiFi direct to send and receive data, look at the following documents:
Intel® Edison - Wi-Fi Guide
Wi-Fi Direct data transfer between two Intel® Edison devices through FTP
There are other interfaces you can use like SPI and I2C, for these you can use the Arduino IDE and its language or you can use the MRAA library for C coding. You can create a script/code that sends packages of data, you may need to send data in different intervals. Please take a look at the following links regarding this library and some examples for C:
I hope this helps.
Thanks a lot Charlie!
