C030 N211 with NBIoT module software version U657 SP2

18 Sep 2017

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 (ublox-at-cellular-interface-n2xx and 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!
