OpenAT App on UART1 Port - AT commands not accepted

Legacy General
1

I complied and uploaded the example given below on WMP100.

This program causing WMP100 to go through restarts. This program opens a flow using FCM to UART1 and tries to switch to Data mode.

WMP100 now does seem to accept any AT command (at+wopen=0; at+wdwl etc) hence I am not able to download another program.

Question: How can we download a new application when the WMP is not accepting AT commands.

I don’t know if there is a newer trick for the WMP 100 but on older modules you would need to flash the core firmware by using the boot pin and DWLWin Tool. This should still work with the WMP 100. I think you should contact your distributor to get the appropriate version of the tool and the core firmware files required.

hi

I find the same probs of not responding of AT commands.
but this arrieved after downloading “Hello_Word” sample.
It work for 2-3 times after that modem stop giving responding any AT command.

mr. jan
Can I get this DWLWin Tool from anywhere.
I am working on Q2406B module

Thanks in advance

I got the same prob with every application.

after debuging the rte version of the OpenAT software, the modem (Q2686) only print out some wind: messages and refuses to accept any at commands. even after a reset or a powercycle. seems to be a problem of the debugger.

the solution for me: start dwlwin (you can download it when you have a login on the wavecom site under product->download->tools) and just mark the piont “erase OpenAT Application”. start the modem with the on/off pin set to bootmode. after this powercycle and the modem is ready from the scratch.

but i think its a bad way to use the tools. the debugger should release the modem in its empty state after debugging …

On devkits, if you hold down the two keyboard switches closest to the board’s edge while booting, your Open AT application won’t start. You can then enter “AT+WOPEN=0” to disable any application causing reboot loops.

hi

thanks fro the response.
i could evalute the problem but not solve it:

if i burn down the firmware, everithing works fine. the target Monitoring Tool is able to connect to the board, i can type in some at-commands in the terminal emulation. after setup the uart2 and start debugging (RTE), everithing works fine.

now its getting strange:

after finishing debugging, the Q2686 starts to write WIND: 13, WIND:0 (no sim card) and WIND:7. after this the Q2686 is invisible to the target monitor tool, and does not accept any at commands on uart1. but it accepts at commands on uart2.

is there any at-command to reset the Q2686 in a way that it is like bevor the first time debugging (RTE)

cheers claudio

ps: i use the newest version of firmware and dev-tools R71
