CC2650: How to enable UART when in RX

Adrian Ymeraj

Part Number: CC2650

Hi all,

my customer has some issues with the CC2650. His project is about wireless sensor networks, namely he is using 2 sensortags (CC2650) connected to the gateway (beaglebone), all done following the approach showed by TI in our Contiki-6LOWPAN page.

http://processors.wiki.ti.com/index.php/Contiki-6LOWPAN

The problem arises once he tries to communicate with another micro-controller from ST (stm8s): how can he enable the UART when in RX ?

As a matter of fact, in the contiki project, for the cc26xx_uart_init() function, it's commented as follows:

/* Only TX and EN to start with. RX will be enabled only if needed */

input_handler = NULL;

Hence the question on how to enable the UART when in RX.

Thanks and beset regards,

Adrian

Try to refer to the sample code in sunmaysky.blogspot.co.uk/.../using-cc13xxcc26xx-running-contiki-os.html

Adrian,

Are you calling the cc26xx_uart_set_input() function?

e.g.

// Enable UART input by registering an input callback function
// serial_line_input_byte() is a pre-defined callback function from "dev/serial-line.h"
cc26xx_uart_set_input(serial_line_input_byte);

// Disable UART input by unregistering the input callback function
cc26xx_uart_set_input(NULL);
