I am trying to initialize the RTC on the STM32L475VG with the current network time, so I would like to use NTP. I am also using FreeRTOS. NTP uses UDP as a protocol and I would like to use FreeRTOS+TCP to connect to this socket. However, FreeRTOS+TCP requires a portable NetworkInterface.c file that I cannot find for the STM32L4 series micro controllers. I was wondering if anyone knew where I could find this file ported to the STM32L4 or if there are already written NTP clients for the STM32L4 series micro controllers.
I am using the DISCO-L475VG-IOT01A evaluation board, which has the Inventek ISM43362 on it. Is there a NetworkInterface.c file that's been ported to this hardware? I know that this WiFi module supports UDP sockets, so I am confused as to why there wouldn't be a NetworkInterface.c port to this device.
The Wi-Fi module requires no operating system and has an integrated TCP/IP stack that only requires a simple AT command set to establish connectivity for your wireless product.
And the same text is written in ST's user manual also. You don't need +TCP, lwIP or any other IP stack - You need USART communication with AT commands.
First You have to get TCP connections working. Then on top of that one way or another You must implement/integrate some kind of HTTP server for web and Telnet or SSH server for terminal.
I appreciate the reply. I did open a ticket with support, asking if there was a echo server example. They told me to contact the chip manufacturer. When I get something working I'll post back.
