Revision History

Version Description
2.6.1
  • Updated ESP8266, ESP32 and WizFi360 WiFi drivers:
    • Added auto protocol selection in SocketCreate
    • Fixed socket default timeout (zero == no time out)
    • Fixed SocketRecv/RecvFrom non blocking mode when received less than buffer length
  • Updated Inventek ISM43362 WiFi driver (version 1.9.0):
    • Corrected Initialize function failure if called shortly after reset
    • Corrected default protocol selection in SocketCreate function
    • Detected STM firmware limitation: SocketConnect does not work if any of IP address octets is 255 (for example IP like x.y.z.255)
2.6.0
  • Updated ESP8266, ESP32 and WizFi360 WiFi drivers:
    • API V1.1: SocketSend/SendTo and SocketRecv/RecvFrom (support for polling)
    • Added DHCP setting before station Activate
    • Added read of DHCP assigned IPs after station activate
    • Fixed serial tx busy flag handling
    • Fixed function AT_Resp_ConnectAP for NULL argument
    • Enhanced serial communication startup procedure
  • Updated Inventek ISM43362 WiFi driver (version 1.8.0):
    • API V1.1: SocketSend/SendTo and SocketRecv/RecvFrom (support for polling)
    • Corrected GetModuleInfo return string termination
    • Corrected functionality when DATARDY line is used in polling mode
    • Corrected SocketConnect function never returning 0 in non-blocking mode
    • Corrected SocketRecv/SocketRecvFrom function polling if called without previous Bind
    • Corrected delay after module reset
    • For non-STM firmware variant only firmware version 6.2.1.7 is supported
