62999	Using Internet Library, If GPIO subscription and power on is done during the I2C bus subscription or read operation, then I2C bus status is sometimes returned as busy. This ‘busy’ status leads to an error while reading of MAC Address.	Internet Library	OTHER	5.56
64959	WIP_CEV_PEER_CLOSE EVENT is not received with the HTTPS in case Server Shutdowns after data channel has been opened.	Internet Library	OTHER	5.56

In this case, HTTP server closes the socket after each request, but Internet Library doesn’t close it on its side. So, if a second HTTP request is sent to the same server, it fails since the connection is closed on the server side.	Internet Library	OTHER	5.56
