Core becoming unresponsive, Timed out

Troubleshooting

@hansamann @BDub

I will have to look at the code, but the cc3000 should be able to tolerate a short periods of the interrupts being off as long as the restoration is conditional on the state of the interrupts at the time of disable.

typedef uint32_t intState;
inline intState DISABLE_INT()
{
  intState is = __get_PRIMASK();
  __disable_irq();
  return is;
}

inline  int ENABLE_INT(intState is)
{
    int rv = ((is & 1) == 0);
    if ((is & 1) == 0) {
        __enable_irq();
    }
    return rv;
}

The other real possibility is a fault that is currently not displayed in the current spark build. Had one my self see

I would try a debug build and capture the Serial1 output using

rm -rf git_master_new
mkdir git_master_new
cd git_master_new
git clone GitHub - Spark-Works/core-firmware: Firmware for the Spark Core, a tiny Wi-Fi development kit.
git clone GitHub - Spark-Works/core-common-lib: Common library for projects that use the Spark Core with the CC3000
git clone GitHub - particle-iot-archived/core-communication-lib: Embedded C++ library for communication between Core & Cloud
cd core-firmware
git checkout spark_master_new
cd ../core-common-lib
git checkout spark_master_new

Then build with make clean && make DEBUG_BUILD=y

The debug output will come from tx,rx 3,3V pins.

Once that works. Update application.cpp to your code and add

void debug_output_(const char *p)
{
  static boolean once = false;
 if (!once)
   {
     once = true;
     Serial1.begin(115200);
   }

 Serial1.print(p);
}

and see what the log says.

log out put will look like:
