[Hilo] Why freeze after <AT+KTCPCNX=1> even after the timer out set by <AT+KCNXTIMER=0,30,1,60>)?
Answer: This behavior seems due to bad network environment.
Before the firmware version of V5.04, <AT+KTCPCNX=1> will try to activate the PDP context but seldom, the network does not answer “yes” nor “no’, in this case no any timer be started internally. So you see no any response. In this case, please try to send any character to abort.
On Firmware version of V5.04, we use an internal 30s timer (T3380) to avoid this issue.
So please update the firmware if you have such issue.
