Hi,
I'm using the CC1352P-2 development kit.
Tried measuring the consumption current while running ble5_simple_peripheral_cc13x2p2lp_app and dmm_wsnnode_remote_display_app_CC1352P_2_LAUNCHXL_tirtos_ccs projects.
In both cases I've disabled the advertise, and also the WSN transmissions.
I'm taking the measurements with a continuous current metwe, with 1mS sample rate.
In both cases the average current is a bit more than 80uA, while the minimum current floor is about 80uA.
In this case I'd expect the current to be around 1uA.
Is there any reason for this high current? Maybe it's the on board FLASH device that should be put into deep sleep?
Is there any other options to add to the project, except the POWER_SAVING ?
Is there anything else that should be done in the project to reduce current?
Thanks, Isak.
Hi Marie,
Here are the energy traces.
It's from the DMM project, where both the TX and the BLE advertisements are disabled.
It's also about the same results I got from the ble5_simple_peripheral_cc13x2p2lp_app asfter disabling the advertisments.
The board version is:
HW: Rev: A
FW: SDK2.10
1825
Thanks, Isak.
So this a a problem of the LaunchPad, right?
Actually I did try to use an external PSU, and got the same results.
I removed ALL the interconnecting jumpers, and connected the PSU to the 3.3V near the SMA connector. That way the CC1352 is totally isolated from the XDS, right?
Is there a reason you recommended to leave the TDX and the 3.3V?
Wouldn't the XDS draw current from the CC1352?
Thanks, Isak.
Yes,
But I used an external PSU and current meter.
And I got about 500uA average current on the external current meter, while all the jumpers are disconnected.
Hi,
That's exactly what I did. The Energy-Trace screenshots at my previous post are without advertising and without any RF activity. Just standby.
Also got about the same results using an external PSU and current meter, and all jumpers removed.
Hi,
I tried the pinStandby demo, and it also gives about 500uA average current, both with EnergyTrace and with an external PSU.
For external PSU, I disconnected all jumpers, and then tried with and without the TX (and GND) connected, and the result is the same.
Thanks, Isak.
