I am trying to run the GenericMQTT Example from the software package in the title.
Path: STM32CubeExpansion_Cloud GenericV1.0.0\Projects\STM32L496G-Discovery\Applications\Cloud\GenericMQTT
I have modified the source code to include a #define USE_BG96 as the CELL02 kit uses the BG96 not the UG96. I am using a truphone global micro SIM (not the embedded sim) in Australia and am able to successfully use the ping examples from the STM32CubeExpansion_CELLULAR_V6.0.0 package using this SIM.
The error message I receive when running the application is

My P-l496G-CELL02 C2C device won't connect.
Problem with firmware package and P-L496G-CELL01 board. why C2C device not connect ?
B-L462E-CELL1 not connecting to TruPhone
B-L462E-CELL1 not connecting to TruPhone continued
SOLVED: I placed the definition for USE_BG96 in
Project --> Properties --> C/C++ Build --> Settings --> Tool Settings --> MCU GCC Assembler--> Pre-processor --> Then hit the little green "+" and add USE_BG96
NOT
Project --> Properties --> C/C++ Build --> Settings --> Tool Settings --> MCU GCC Compiler --> Pre-processor --> Then hit the little green "+" and add USE_BG96
And so USE_BG96 was not correctly defined.
