We have a problem with the very simple Hello_World example provided with Open AT V400.a03. (Wismo Quick development kit)
We’ve compiled this example using GCC according to instructions in OpenAT tutorial and then successfully downloaded it to
Q2686 Wireless CPU. However, after issuing AT+CFUN=1 and AT+WOPEN=1 commands nothing happens.
The AT command still works so the modules doesn’t seem to hang, but we never get the “Hello World” output
+WOPEN: 2,“AT v04.00”,“AT v04.00”
Here the complete serial output trying to run the HelloWorld example
