CC1352P: zed ota has higher consumption

Hi Howjie,

I know that we have covered the non-OTA cases in a previous E2E thread.  Have you followed all instructions in the Z-Stack User's Guide -> OTA Upgrade section in regards to loading the BIM hex and Client OTA application binary consecutively?  Can you confirm that the device is operating as intended (i.e. commissioned in the network and polling for data), either through the UI or over-the-air packets?  You may want to reduce polling frequency, remove the UI (i.e. UART and LEDs), and measure after the joining/F&B time has passed.  What tool are you using to measure power consumption (like EnergyTrace as before), are you removing all XDS110 jumpers (if using a LaunchPad), and can you confirm that sleep is actually being entered?

Regards,
Ryan

Hi Ryan,

I found a post discussing the same issue:

https://e2e.ti.com/support/wireless-connectivity/zigbee-thread-group/zigbee-and-thread/f/zigbee-thread-forum/795285/cc1352p-how-to-use-rcosc-with-simplelink_cc13x2_sdk_2_30_00_45-zstack/2959057#2959057

The poster claimed that it was resolved by setting SET_CCFG_MODE_CONF_SCLK_LF_OPTION=0x3 in the BIM project. Howjie tried this but had no luck. Can you please help suggest what else could we try?

Thanks.

Best regards,

Can you post screenshot of energy trace when you do OTA and see this issue?

Hi Ryan,

"I know that we have covered the non-OTA cases in a previous E2E thread. "

The current when the device is sleeping is normal in the previous E2E thread, but the power consumption in Rejion exceeds expectations. At present, we don't know how to deal with this problem.

We are using OOB zed_sw_ota_client and bim_offchip project, do we also need to make special changes?

The device joins the network and polling for data is normal, and I haven't started OTA when I measured the power consumption.

I use EnergyTrace and other tools to measure power consumption, and there is no big difference in the power consumption data obtained. When the device is not connected to the network, the sleep power consumption position I measured is as shown in the screenshot below:

The situation after the device is joined to the network is the same.

Thanks,

Howjie

Hi Ryan,

We use the SDK 5.20 project. The power consumption is normal.

Thanks,

Howjie
