Hi,
I have PPP working on an HL7692 but when I crank the baud rate (via AT+IPR) to 230400 it falls over. The connection establishes OK by then I get several Tx retries and the link goes down, indicated by the bold line below. I suspected h/w handshaking was not working but I have configured AT&K3 and AT+KSLEEP=2 and I can see CTS changing. I am using Keil’s USART driver which has h/w flow control enabled. I realize it’s likely to be a problem my end but I am just making sure there is not a known issue with the HL7692 module. Has anyone used PPP at > 115200 baud successfully?
