CC1350 and UART_CMD_RXDISABLE command

Matteo Sartori

Other Parts Discussed in Thread: CC1350

Hi everybody,

I'm using CC1350 Launchpad with 6.2.0.00050 CCS and 2.20.0.06 TI-RTOS.

I'm using UART with UART_MODE_BLOCKING, it works, but I'm trying to use the UART_CMD_RXDISABLE command to permit the system to enter low power modes, with the command:

UART_control(uart, UART_CMD_RXDISABLE, NULL)

but it seems it's not implemented, I get a -2 error value (UART_STATUS_UNDEFINEDCMD).

Have you got any ideas?

What would you do to get low power modes? I'm always on active or idle mode, I measure 1.1mA consumption, but I need standby or shutdown mode.

Thanks.

Best regards.

Hello Matteo,

Yes, it does not look like the UART_CMD_RXDISABLE has been implemented. I do not see the implementation in the file C:\ti\tirtos_cc13xx_cc26xx_2_21_00_06\products\tidrivers_cc13xx_cc26xx_2_21_00_04\packages\ti\drivers\uart\UARTCC26XX.c

Can you try closing and reopening UART as a work around?

Regards,
PS

Hi,
ok, I've tried and it works. I hope RXDISABLE will be implemented because it would be very useful.

Thanks.
Best regards.

Glad to hear that it works now. Apparently the common API that includes UART will be the same across a multitude of TI processors. The underlying implementation is different and CC13xx has RXDISABLE not implemented yet. I will raise a ticket to have this done for CC13xx processors. Thanks for bringing this up.

Hello Matteo,
Thanks for the follow up. The ticket has been filed and the next release should have this fix. We apologize for the delay.
