Hi Makers,
I am using RFID device with Particle Cloud service on Electron. I got some errors when I try with Sample code MFRC522_Dumpinfo.ino
I add command “Particle.function(“Alarm”, AlarmToggle);” with related standard code for this command such as AlarmToggle and my handler functions
The error syntax show
Line 1
../wiring/inc/spark_wiring_cloud.h:191:25: no matching function for call to 'CloudClass::_function(const char [6], String (*&)(String))'
Line 2
../wiring/inc/spark_wiring_cloud.h:191:25: invalid conversion from 'String (*)(String)' to 'int (*)(String)' [-fpermissive]
When I expand full error, it indicated

May you figure the problem and share idea for solving the error?
Thanks you
