My peripheral device stops advertising after a day or so

Other Parts Discussed in Thread: CC2541

I have a CC2541 design based on the postage stamp design. The software is based on the SimpleBLEPeripheral project to which I added a simple service with some characteristics. I am using the 1.4.0 stack and IAR EWB 8.30.2

So far the device has not managed to stay up for more than a few days. usually after a day or so the device stops advertising and requires a powercycle to get back. There is no specific trigger like connection events.

Any ideas for troubleshooting this?

    Hi Ben,

    Hard to say with such little details. You should  analyse fast are you advertising (advertising interval) and also make sure that you are using power management (enabled by define POWER_SAVING). If you are bursting advertisements every 100ms, expect low battery life time, while 1s might give you battery life 1 year++.

    Please refer to this Application note AN092 on how to measure and estimate battery life.

    Best Regards
