BLUE TOOTH LOW ENERGY

I have couple of queries Regarding the BLE.

1. In sleep mode if im advertising an event at pulse duration of 10ms in 1sec or 5 sec or 15 sec or 30 sec , what is the minimum average current consumption with respect to each of the interval specified above.
2. Whether the TX current(3.7mA) mentioned in the datasheet is same as the advertising current considering all peripherals are non functional.
3. Can you explain on sequencing of ADC on 4 channels for this part.
4. Im looking for Trace antenna for my application with this BLE, What will be the dimensions of antenna required with this BLE typically to transmit the data for 1-3 foot distance,

Hi GREESHMA KV,

Hi GREESHMA KV,

1 – 2) If I understood correctly, your question is regarding the minimum current consumption of the TX? As you mentioned, the TX current consumption is 3.7mA. Could you please explain what you mean with “as the advertising current considering all peripherals are non functional” ? If I misunderstood something, please let me know

3) I am not able to understand what you mean, can you please clarify your question?

4) Regarding you last question, I would suggest you to have a look at the AN-B-027: Designing Printed Antennas for Bluetooth Smart.  Also, you could find dxf files by following this link AN-B-027: Designing Printed Antennas: DXF files.

Thanks, PM_Dialog

1-2) What I was trying to ask

1-2) What I was trying to ask is , what is the minimum current consumption during adverting an event in 1 sec , 5 sec, 15 sec etc by the BLE when BLE is in sleep mode.

Hi GREESHMA KV,

Hi GREESHMA KV,

I would strongly recommend you to have a look into Tutorial 4 : configuring sleep mode on DA1458x tutorial from our support portal. In this tutorial you could find all the measurement into the sleep modes. Also, you can use the power profiler in order to measure by your own the current consumption.

Thanks, PM_Dialog
