AT^SIST retunrs ERROR? | Thales IoT Developer Community

Hello everyone,

We are working with HSE6 (revision 02.000)  sending AT commands thru serial port. In our develop, we success sending small  blocks of data (<1500 bytes), but now we need to open a transparent connection to send a huge amount of chars (about 3000) from our mobile device to a server in one block (no slices), because time matters... 

But AT^SIST always return ERROR...:

AT^SICS=0,conType,GPRS0

OK

AT^SICS=0,user,MOVISTAR

OK

AT^SICS=0,passwd,MOVISTAR

OK

AT^SICS=0,apn,"movistar.es"
