"+CME ERROR: 841" is received in place of "+CME ERROR: 842", if an invalid FTP server name is given while establishing FTP session.
5.56
59405
The +CME ERROR: 837 received instead of +CME ERROR: 831 when the command AT+WIPDATA is issued without creating any bearer or socket.
64806
Internet bearer opens successfully even if the Internet stack is stopped using AT+WIPCFG=0.
65593
Connecting and disconnecting a socket in a loop, using Internet Application, leads to a reset.
55783
Functions of Security library not called if an application links to both Internet and Security library.
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.
64959
WIP_CEV_PEER_CLOSE EVENT is not received with the HTTPS in case Server Shutdowns after data channel has been opened.
65832
Using Internet Library, When a GET Request is sent from SNMP manager to SNMP agent before getting the response of the previously sent GET request, then AirPrime freezes.
65853
When SNMP session is closed using the API wip_snmpClose(), the AirPrime resets.
66608
WIP_CEV_PEER_CLOSE event is not correctly managed by Internet Library when HTTP client is used on a non-persistent HTTP server. 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.
