The following corrections/changes have been made:
3.5.2.4 Release
 1. Fixed hang in SPI when server not available for TCP-SSL. 
    Note: Timeout averages 37 seconds for 'P9=2' and 19 seconds for 'P9=0'. 
 2. Fixed issue with 'C0' command not setting the DNS servers in the 'P?' command. 
 3. Added the functionality of returning the number of bytes to the host
    as set by the ‘R1’ command for TCP-SSL/TLS. 
 4. Corrected the S0/S3 check for TCP-SSL/TLS for the socket being close
 5. On closing (P6=0) of a SSL(TLS) connection corrected issue
    in context reset and indentity deinit.
 6. Fixed SPI prerformance issue
 7. Fixed memory leak in TCP-TLS
 8. Fixed S3 command check if socket is connected berfore sending
 9. 'P6=1' command checks for invalid IP address.
 10. Fixed 'RX Unhandled Socket EC = 5' in 'R0' command
 11. Improvements in UART host interface thourghput.
 12. Added 5GHz to 'AC'(Auto-channel) command
     AC - <0-Auto Chnl 2.4G, 1-11, 50-Auto Chnl 5G, 36-48 x4, 149-165 x4, Country dependent> Set AP Channel
	 Note: 5GHz Auto-channel only works on modules with a 5GHz radio like ISM43340-M4G-L54.
 13. Added 'F6' command for setting the Band to scan with the 'F0' command
     F6 - <0=5GHz, 1=2.4GHz, 2=Both(Default)> Set Scan Band
	 Note: 5GHz only scan only works on modules with a 5GHz radio like ISM43340-M4G-L54.
 14. TCP Maximum segment size(TCP-MSS) is set to 1452 bytes which can result in a of 1460
     packet broken up into two packets of 1452 bytes and 8 bytes. 
 15. Fixed issue with multiple TCP-SSL sockets where the 2nd socket was not setup 
     correctly eventually causing a read or write failure to occure when switching between 
	 two sockets.
