The peripheral manager that sends characteristic value updates.
When a call to the
update method fails because the underlying queue used to transmit the updated characteristic value is full, Core Bluetooth calls the
peripheral method when more space in the transmit queue becomes available. You can then implement this delegate method to resend the value.
