FYI, in the past I have found that switching on any logging in the LWIP stack tended to drop data so I don't do that anymore.  The _usual_ reason for not establishing a PPP connection is that the APN is wrong; if you leave it unspecified for the U201-flavour C030 board then the APN database in the driver will find the correct one (jtm2m)."}}
