Answer 1

The main problem seem to be that it is a buffer problem on the chip you are using. From the core specification, Volume 3, Part F, 3.3.2:

For notifications, which do not have a response PDU, there is no flow control and a notification can be sent at any time.

Commands that do not require a response do not have any flow control. Note: a server can be flooded with commands, and a higher layer specification can define how to prevent this from occurring.

Commands and notifications that are received but cannot be processed, due to buffer overflows or other reasons, shall be discarded. Therefore, those PDUs must be considered to be unreliable.
