Hi Alan, Unfortunately ublox does not, maybe Nordic does, but i dont wish to reflash the module. What i am thinking is to implement an u-connect parser similar to the NMEA parser (GPS parcer) and implement it in utils in apps, in this way i wont disturb the already existing Bluetooth functionality and add support for ublox devices which use u-connect, they have also Wifi and other modules which use u-connect so i think it will be nice addition to have this parser in Nuttx.
