Hello,

I'm developing a device run on coin cell battery with CYW20737S.

I've managed to set lowest TX power -20dBm, advertisement interval: high 100ms for 5 sec, low 640ms for 5 sec.

Now I would like to estimate battery life based on these settings. I read the datasheet but haven't found any clue on how current consumption related to TX Power level (?).

The only parameters mentioned in the document is below table, which is general without a specific condition of radio TX power.

Could you please help provide with more detail on current consumption of the device during advertisement?

Thank you in advance.

Best,

JS

We haven't got these figures but I noted that there are some calculator apps in the internet that attempt to estimate the battery life of coin batteries. You may need to measure the average current drawn of your product over a period of time, say an hour.
