BLE 5 power consumptions

[Vikindio]

Hi Nordic.

I have received here in Norway my first batch of BLE 5, and we are about to start developing and building our wristband with the only purpose of monitoring/positioning. I need to know what will be the consumption of the whole BLE and our SoC for it. Its about 15mm diameter and using a button cell battery that we are still to determine, but we wish it could be CR12xx and no bigger that the CR20xx cell battery. The BLE will have a 10secons on/off interval and only to pin its position, no more than that. Could you give me an estimate of time of that full wristband working? I have seen the consumptions of the Rx and Tx lower than previous, and taking a CR20xx that can give 230mAh divided by the consumptions (xxxxxxmA) of the wristband= 6month to 12 month IS OUR GOAL. What would you suggest us? thanks in advance for your help. Ronny

Surprise: you will need to build a proto and measure it:) You can do some very rough estimate with nRF52 on-line power profiler but in the end you will build a prototype and measure it.

Thanks! What you mean when you say "won't be your single issue, trust me" ? I trust you :) but I would like to hear the whole thought. Im into a serious project here, installing a system on a big vessel and trying to find the best way out for the build of this wristband that will monitor the crew. I will deeply thank you for all the insight you can share with me. Thanks again. Ronny
