Versions

Version	Release Date
WiConnect-2.4.0.7	Oct 23, 2015
WiConnect-2.4.1.5	Jan 14, 2016

Last Updated : Jan 18, 2016

All known issues in v2.4.0 have been fixed in the v2.4.1 release, other than the following:

Description	Solution or Workaround
1. High throughput data using command mode When transferring high-throughput data in command mode, a byte may be dropped after transmission of large data blocks.	Increase bus.command.rx_bufsize and lower bus.command.write_timeout to avoid any additional delay due to command response latency.

v2.4.0 : Changes for v2.4.0 are listed in the following table.

Topic	Description
HTTP	Added error message for http_download indicating `Content_length` header required
Ping	Improved compliance of module response to ping from another module

Stream mode	Removed an incorrect prompt from information messages in stream mode
TLS	smtp_send now works with SMTP servers that require TLS 1.2 security
UDP	Fixed a problem where the UDP server repeated received data
	WiConnect now sends UDP packages up to the full MTU size and no longer chunks messages into 128 byte packets.

Security	Support for Microsoft Azure authentication
System Monitoring	Added a system monitor fault that triggers immediately.
GPIO	Fixed a problem in Stream mode where OOB GPIO was not set when data available
GPIO	Fixed a problem where GPIO5 PWM was not working on AMWx06 platforms
HTTP	Fixed a problem where HTTP requests returned no data which the command interpreter was blocked by an interrupted REST command
Web App	Fixed a problem where unset web app strings were not initialized to empty strings.
Setup	Fixed a hard fault condition that occurred when using setup.gpio
TLS	Fixed a problem where a TLS connection was sometimes prematurely closed while data was still available to be read.
