Uart close problem

luch1990 · April 8, 2014, 12:43pm

Hi!
I have a problem in my project. I use FCM to communicate with external devices. Everything works well. But at the end of the program I can not close the port!!! After switching to AT MODE I get event ADL_FCM_EVENT_V24_AT_MODE. Then I call the function adl_fcmUnsubscribe (rs232_state.handle) and get event ADL_FCM_EVENT_FLOW_CLOSED. Next I close the port using the command “AT + WMFM = 0,0,1” and get error answer: “+ CME ERROR: 3.” Port stoped only when the application is stopped (AT+WOPEN=0). Module SL6087, FW: 7.46. How i can close port??? Help please!

Main:

one question here…

where are you issuing AT+WMFM command??

Is it thru application or thru hyperterminal?

luch1990 · April 10, 2014, 5:07am

After switching to the AT MODE I call a function adl_fcmUnsubscribe. Then in application I execute command:

adl_atCmdCreate("at+wmfm=0,0,1",ADL_PORT_OPEN_AT_VIRTUAL_BASE,poll_answer_uart1_off,"OK",NULL);

It returns OK, but poll_answer_uart1_off not called (((. After that in hyperterminal through USB i execute a command AT+WMFM=0,0,1 and get “+ CME ERROR: 3”. UART1 is not closed. But UART2 closed successfully. If i use UART2 in my application, UART1 closed successfully, UART2 - unsuccessfully. I twink, problem in using FCM. If a program does not run FCM, ports are opened and closed successfully.

luch1990 · April 11, 2014, 12:46pm

I have a new problem. I do not understand why, but when executing:

adl_atCmdCreate("at+wmfm=0,0,1",ADL_PORT_OPEN_AT_VIRTUAL_BASE,poll_answer_uart1_off,"OK",NULL);

, the controller restarts (even function does not return a result. none at all). why the controller may reboot when the standard command called from the application??? (Sorry for bad english )

Rex_alex · April 16, 2014, 11:53am

Ok… i’ll run the FCM appplication at my end and will check it…
you said giving AT+WMFM=0,0,1 give CMEE error -3
Just before executing this command can you check the response of AT+WMFM?

Just a guess… i think it’s already closed may be… and you are trying to close it again…

Regarding the reset… are you getting any backtraces?

also, try with some latest FW 7.52…

7.46 is pretty old…

Thanks
