Tool/software: TI-RTOS
Hi everyone,
I'm having a problem with the power consumption when using launch pad cc2640r2f chip.
Expected:
When running the “micro-eddystone-beacon” of CC2640R2 Texas Instrument example, I expect to have a 1uA base consumption.
Result:
When monitoring the consumed power with the PPK (power profiler kit PCA63511 of Nordic) we have a base consumption of 220uA (it’s the best we got after tuning the example).
Tried:
We have referred to the following documentations:
- PowerManagment: www.ti.com/.../sprui20.pdf
- Measuring BLE Power consumption: www.ti.com/.../swra478c.pdf
From these we have tried the following test
Test 1: Adding these lines to the program, disconnecting all the GPIO + Debugger, commenting out all tasks
/*--------initialization power policy---------*/
Board_initGeneral();
Power_enablePolicy();
Power_setPolicy(PowerCC26XX_standbyPolicy);
/*--------fin initialization power policy-----*/
//force mode standby
Power_sleep(PowerCC26XX_STANDBY);
Result 1: power consumption drops from 5mA to 220 uA
What can I do to have a 1uA base power consumption with the cc2640R2F ?
Thanks in advance!
