Not likely, it may however be that iOS re-enable them somehow, but in any case DM_GATT_CCCD_COUNT should be increased in this case.

Hi Kenneth,

I just program the HID Keyboard example and whille for IOS it was not needed to update the DM_GATT_CCCD_COUNT because it reconnected perfectly for Android it was neccesary. Does Android use more characterisitic notifications than IOS?

Thank you in advance.

Hi, the DM_GATT_CCCD_COUNT should be set to minimum the number of characteristics you have that support notifications or indications. Also take into account that you may have a service changed notification enabled in the softdevice.

I am going to answer to myself.

The issue was solved by incrementing the DM_GATT_CCD_COUNT.

I don't know exactly why this solved the issue.
