When I try ping a given server, using the url not the IP address, I get the following error:
AT+WIPPING="www.isr.ist.utl.pt",1,200,4500 +CME ERROR: 24
This is strange. The error means “text string too long” (page 84 of the user manual, WA_DEV_WISMO_UGD_912 Rev003).
I can ping, without a problem, any sites with shorter urls. Is there a limitation to the size of the url in the ping command ?
