CC2642R: Is it possible to disable the UART interface for simple peripheral?

Part Number: CC2642R
Other Parts Discussed in Thread: SYSCONFIG

Hi，

How to disable the UART interface in the BLE examples like simple_peripheral in simplelink SDK? Is there a predefined symbol for this? I'm using the latest simplelink_cc13x2_26x2_sdk_4_30_00_54.

And I found the description of the APP build configuration in the readme file of simple_peripheral example saying that "The application uses the config file ble_release.cfg and the defines are in <app name>_FlashROM_Release.opt", however I can't find the ble_release.cfg or <app name>_FlashROM_Release.opt file in the project folder. What is the path of these files?

Thanks.

Best regards,

Shuyang

    I believe the file paths for ble_release.cfg and cc26x2r1lp_app_FlashROM_Release.opt are simplelink_cc13x2_26x2_sdk_4_30_00_54\examples\rtos\CC26X2R1_LAUNCHXL\ble5stack\simple_peripheral\Tools and simplelink_cc13x2_26x2_sdk_4_30_00_54\examples\rtos\CC26X2R1_LAUNCHXL\ble5stack\host_test\tirtos\ccs\defines, respectively.  cc26x2r1lp_app_FlashROM_Release.opt is where NPI_USE_UART is defined.

    Hi Ryan,

    Thanks for the tips. I am able to find ble_release.cfg in simplelink_cc13x2_26x2_sdk_4_30_00_54\examples\rtos\CC26X2R1_LAUNCHXL\ble5stack\simple_peripheral\Tools by your instruction, but after importing this project into CCS, I found that this file was not imported, only ble_Release.xscfg was under the Tools folder of the project. I'm a little confused about these 2 files (ble_release.cfg and ble_Release.xscfg), can you please explain what the .xscfg is for?

    For <app name>_FlashROM_Release.opt, I'm not using the host test project, by <app name> in the readme I think it means simple_peripheral_FlashROM_Release.opt or something like that, but I can't find such file in the project folder, there is only a config_def.opt under \Tools\Defines, is it what the readme refers? If not does the simple_peripheral example provides similar option as the host_test?

    I opened the config_def.opt file and there are only 3 configs in that file:

    --config_def CC2642=1
    --config_def PAGE_ALIGN=-1
    --config_def FLASH_ROM_BUILD=2

    So does the simple_peripheral provide a predefined symbol to enable/disable the CUI? Thanks.

    You can add Display_DISABLE_ALL to predefined symbols to disable UART console.

    Hi Yikai,

    Thanks, this works.

    And I have found in the migration guide from BLE5-Stack 2.00.04 to BLE5-Stack 2.01.00 that project_name_app.opt has been replaced by ti_ble_app_config.opt because of the Sysconfig, and the display can be disabled from BLE->Advanced Settings->Disable The Display Module in simple_peripheral.syscfg. It has the same result as the predefined symbol by adding Display_DISABLE_ALL in the ti_ble_app_config.opt script.

    I guess the readme has an out of date statement for this which leads to the confusion, hope this gets updated in the coming versions.

    BR,

    Actually, the display can be disabled from BLE->Advanced Settings->Disable The Display Module in simple_peripheral.syscfg too.
