I guess I meant the SpiFlash25 library that talks to the serial flash on the dragonfly B01 boards?
I am using the cat-1 dragonfly mbed version.
I am using the examples but they are all TCPIP
No sms or GPS required.
I am pretty sure I am using MBED OS 5
I finally got udp working after a lot of trial and error guessing.
No help looking at the cellularinterface or modeminterface libraries from Multitech
