<div dir="ltr"><div>Hi Reinhard, </div>thanks for the suggestion. Yes, +CPINR is not supported by all Telit modems (e.g. LE910 and LE910 V2), so I opted for the command with wider support. Changing the timeout can be a solution and I'll made some tests. </div> <div class="gmail_quote"><div dir="ltr">On Mon, 13 Mar 2017 at 22:42 Reinhard Speyerer <<a href="mailto:rspmn@arcor.de">rspmn@arcor.de</a>> wrote: </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On Mon, Mar 13, 2017 at 03:48:51PM +0000, Carlo Lobrano wrote: > Hi Salvador, > > I'll look into this CSIM lock thing, but with a newer FW version I'm > actually getting responses to CSIM and the next messages (see logs below). > Hi Carlo, I performed some manual testing with a HE910-G running firmware 12.00.008 and a o2 DE SIM (not USIM) today and while the mobile always responds to AT+CSIM the second AT+CSIM takes much longer before returning the response: at+cpin="xxxx" OK # first AT+CSIM completes in less than 0.5 seconds AT+CSIM=10,0020000100 +CSIM: 4,"6E00" OK # second AT+CSIM completes in about 8 seconds AT+CSIM=10,0020000100 +CSIM: 4,"6E00" OK +PACSP1 Perhaps it might help to increase the corresponding timeout for this step and only use AT+CSIM if the mobile firmware does not support AT+CPINR. AT+CPINR also returns the correct status for a SIM (which the AT+CSIM method currently doesn't): at+cpinr="SIM*" +CPINR: SIM PIN,3,3 +CPINR: SIM PUK,10,10 +CPINR: SIM PIN2,3,3 +CPINR: SIM PUK2,10,10 OK Regards, Reinhard </blockquote></div>
