We are trying to open an HTTPS session with mutual authentication to perform a GET operation from HL6528RD (FW version: 18.104.22.168).
When we send AT+KHTTPSGET command, we have big latencies, i.e.:
- average 20s to have CONNECT response
- average other 20/30s to have the response itself (GET content)
An example of the AT commands we are using:
AT+KHTTPSCFG=1,“server_url”,server_port,0,7,3, , ,1
This happens with or without server/mutual authentication, and with different servers.
If we do the same with e.g. postman, it takes about 1-2s to have the overall response.
What may it depend on?
Thanks in advance,
