CC2650: Modify 'cc26xx-web-demo' to receive data from a Raspberry-Pi

Bawanee Ragavan

Part Number: CC2650

We have created a mesh network using cc2650 nodes. The leaf nodes use 'cc26xx-web-demo' and the border router uses 'ipv6/slip-radio' examples. Border router is connected to a PC where 'native-border-router' is running.

Our task is to input some numbers from a Raspberry-Pi to a leaf node using a serial communication method (we are planning to send the data through the I2C, SPI or UART interfaces of Raspberry Pi) and receive those numbers at the PC through the Border router (using CoAP requests).

Can anyone help us by suggesting a suitable method out of above (I2C / SPI / UART) and please let us know how to modify the 'cc26xx-web-demo' example in order to obtain the data as a CoAP resource.

Hi,

Which contiki repository are you using?
It's recommended to use contiki-ng: .

My understanding is that cc26xx-web-demo shows a demo of reading various sensors on the CC2650 sensor tag, and providing them as a coap resource. Consider using this as a basis for reading your sensors.

Which serial interface (I2C, SPI, UART) is highly dependent on what the sensors themselves support. Each of these peripherals is supported on CC2650, as mentioned in its data sheet: .

Regards,

Toby

You can try to refer to to modify the 'cc26xx-web-demo' example in order to obtain the data as a CoAP resource.

Hi,

I am using contiki OS. Can I know what kind of modifications need to be done in 'cc26xx-web-demo' in order to read a serial input? Or is there any document with the way to modify the codes in contiki?

Hi,

I have gone through the example given. Still I can't find how to modify this in order to read a serial input instead of this DIO23.

Try to refer to but I remember cc26xx-web-demo already implements UART read capability.
