No longer seeing data from sim800l and pic18f4525
No change in the API. My guess is connectivity. Try moving the device to a new location.

MATLAB code has not completed execution within the allocated time. Consider optimizing your MATLAB code to execute within the available time limit.
I suggest using thingSpeakRead and the Alerts service. Your code will preform much faster and you wont have these errors.
