CC2541: Can't connect CC2541 with Os with POWER_SAVING mode

duy dongoc

Part Number: CC2541

dear all,

I used HIDEmuKbd project in BLE 1.4.2.2 and cc2541 module as attached picture.

I tried with default option, when start, module is into sleep mode and wakeup after pressing any button, OS can find HID keyboard in list bluetooth device but CAN'T connect it

When I remove POWER_SAVING macro, OS can find and connect with it.

What is my mistake in this case ??? I need save my batterry.

Hi Duy,

The module you are using does not seem to have a 32 kHz crystal mounted. If that is really the case, you will not be able to go to power down.

Regards,
Fredrik

Dear Fredrik,

Thanks for your support, my module doesn't have 32 kHz crystal and after adding crystal, it is working fine with POWER_SAVING

Thanks & best regrads,

Duy
