I’m using the HL8548 now. Will change it to RC series soon.
But anyway, I have communicate with the HL8548 by serial.
All of sequences are working well.
When I try to connect AT+KTCPCNX, sometimes return the message KTCP_NOTIF.
-It has various reason to get a message KTCP_NOTIF. Network error(0), TCP disconnection(4), TCP connectioon error(5), etc…
At that time, I tried to close the session by AT+KTCPCLOSE. But it has return the message “ERROR”.
Which one is right when got KTCP_NOTIF?
KTCPCLOSE or KTCPDEL?
