CC2652P: How to turn off CC2652P power amplifier?

Hi,

Thank you for reaching out.

Can you check whether Rogelio's comment here could help?

Best regards,

Hello Clement,

Good day.

It looks like some of Rogelio's answer is removed, specifically an image in the middle of the post, before the line of code. Do you know what line I should change here? This is a screenshot from the ble_user_config.c file that Rogelio mentioned.

Also, we would like to know if this workaround will help reduce energy consumption. Or will it just fix the build error? 

Regards,

Hello,

The potential workaround was changing line 424 to the following.

#if defined(EM_CC1354P10_1_LP) || (RF_BLE_TX_POWER_TABLE_SIZE == TXPOWERTABLE_2400_PA5_SIZE)

I will ask the radio team if this indeed helps lower power consumption.

Kind Regards,

Rogelio

Hello Rogelio,

Good day.

I think I might need to ask a more general question about how to lower the BLE current consumption on my CC2652P chip. When I run a non-Bluetooth example on the chip it uses less than 1 mA, and when I run an example with Bluetooth (project_zero, simple_peripheral, etc.) it uses 10+ mA.

Hi,

It would make sense when running a BLE example the power consumption would increase especially if using a higher power

If you go to section 8.10 Power Consumption you can see the expected consumption of receiving or transmitting over BLE.

I would also recommend you check out the Power Calculator https://www.ti.com/tool/BT-POWER-CALC

And here is a thread where jan gives more specific on how optimize power consumption.

Kind Regards,
