CC2340R5: sleep mode to again wakeup mode

Part Number: CC2340R5
Other Parts Discussed in Thread: UNIFLASH,

Tool/software:

HI team,

We are working on sleep mode to wakeup mode, where I'm facing some issues,

Using base project basic_ble_oad_onchip_LP_EM_CC2340R5_freertos_ticlang ,we enabled peripheral +observer

1)Directly its not flashing from CCS IDE (IDE12.5.0 and SDK 7.4.0),But through Uniflash application we can able to flash

2)->If we use shutdown mode 

        1.Advertisement getting stopped and disconnected from connected mobile

        2.scanning also stopped .

             -> If we wakeup using button interrupt, its connecting back and started scanning.

3)->IF we use sleep mode 

        1.Advertisement getting stopped and disconnected from connected mobile

        2.scanning also stopped .

              ->If we wakeup again it not waking up

Whether, It's possible to achieve Radio On in sleep mode.

Can you give some suggestions regarding sleep to wakeup mode and provide some documents or API's which is useful for our understanding and further development.

Thanks and regards

  • Hello Chandra,

    Thanks for reaching out. Please help me with the following questions:

    1. Is this an automotive application? Are you using CC2340R5-Q1 devices?
    2. May I ask how you are configuring either shutdown mode or sleep mode in your project?

    Regarding OAD in general, I would suggest taking a look at this training material: https://dev.ti.com/tirex/explore/node?node=A__AbMoFvWD.bZAg65tD.7NsQ__SIMPLELINK-ACADEMY-CC23XX__gsUPh5j__LATEST

  • Hi David,

       1.Is this an automotive application? Are you using CC2340R5-Q1 devices?

       YES, its an automotive and we are using cc2340r5-q1 device.

      2.May I ask how you are configuring either shutdown mode or sleep mode in your project?

      We are trying both for calculating the current consumption but we need Radio ON during the switching to low power modes,

       we have tested with the launchpad using basic_ble_oad_onchip_LP_EM_CC2340R5_freertos_ticlang  project with help of gpioshutdown_LP_EM_CC2340R5_freertos_ticlang project. During this testing we have observed that in  both modes radio is getting OFF,

    Could you kindly suggest, how to achieve Radio ON in low power modes / advice the other ways to handle this.

    Thanks and Regards
