Dear Jorgen,

Thank you for your reply.

By using "Online Power Profiler for BLE", I could know the current consumption in advertising.

> ISTART,TX is the current consumed by the radio while it is being started (before it starts transmitting). The currents for when the radio is transmitting is the I_TX currents found further above in section 23.15.2. For instance, I_TX,PLUS4dBM (16.6 mA) is the run current when the radio is transmitting at +4 dBm output power and using LDO regulator.

I understand your reply.

Best regards,

Sugiyama

Hi,

I would recommend you to have a look at out Online Power Profiler for BLE. Here you can specify various parameters for your setup, including advertising/connection, output power, chip type, regulator, package payload, and so on, and get the average current consumption for that setup.

The individual currents for each part of the radio activity is also shown in the current diagram.

ISTART,TX is the current consumed by the radio while it is being started (before it starts transmitting). The currents for when the radio is transmitting is the I_TX currents found further above in section 23.15.2. For instance, I_TX,PLUS4dBM (16.6 mA) is the run current when the radio is transmitting at +4 dBm output power and using LDO regulator.
