cc2540 simple peripheral power consumtion

Other Parts Discussed in Thread: CC2540

Hello all,

In a current project working with both msp340 and cc2540 ble, wanting to get the lowest possible power consumption. the msp340 will be in charge of most of the operation and leaving the 8051 only to hable the ble,

Still the ble acts as a simple peripheral project, needing it to be connectable in all times. last time I checked the power consumption was around 8ma (!!!),

does enabling the power modes in the pre-processor configuration is enough for the simple peripheral project? keeping in mind it still has a periodic event going every couple of milliseconds.

    Hi,

    I measured 45 mA with the simple peripheral project. Reason was that the CC debugger was connected. By unplugging the connector I was able to solve this problem. It took me two coin cells to find what happened here. Just make sure that you do not measure the current consumption of the CC debugger. If this is not your problem, I just can report that I am measuring a current consumption in the order of 1 mA. Without advertising I see 0.25 mA.
