It has come to our attention that the very latest version of the firmware for the NBIoT module on the ##UBLOX_C030_N211## boards has a modification to the AT commands associated with IP sockets commands, specifically ##AT+NOSCR##, ##AT+NSOST## and ##AT+NSORF## will now require/put double quotes around the string portions of their parameters in order to make them V250 compliant, e.g.: * ##AT+NSOCR=”__DGRAM__”,17,45## in this command ##DGRAM## is of type string so should be given in double quotes else error code will be issued. * ##AT+NSOST=NSOST=<socket>,”<__remote_ip_address__>”,<remote_port>,<length>,”<__data__>**”## in this command ##<remote_ip_address>## and ##<data>## should be given in double quotes else error. * ##AT+NSORF## in the response string of this command, ##<remote_ip_address>## and ##<data>## will be returned in double quotes. The Cellular API drivers ([[https://os.mbed.com/teams/ublox/code/ublox-at-cellular-interface-n2xx/|ublox-at-cellular-interface-n2xx]] and [[https://os.mbed.com/teams/ublox/code/ublox-cellular-base-n2xx/|ublox-cellular-base-n2xx]]) have not yet been update to handle this. Update versions of the drivers will be posted tomorrow (19 September 2017),

The **N2xx** Cellular API drivers have now been updated, apologies for the delay. The firmware on the **Sara-N211** module MUST BE AT LEAST: ##06.57 A01.02## ...to work with these drivers.

Hi, Could you please point me to the place where I can find the updated version of ublox-at-cellular-interface-n2xx and ublox-cellular-base-n2xx. Thank you!
