I have been searching high and low but not having much luck. I have check the Doc’s and examples but still not working. Maybe its not possible. I dont even have a sample code to show because I’m not even close.
I am using a Particle with a relay attached and using SMS to turn the relay on and off. All is working well.
What I want to do now is have a “alert phone number” (the users phone number) stored in EEPROM so that several units can run the same software.
The particle when powered up sends a SMS to the alert number to sat it has booted up. (currently working with a phone number defined in the code)
I want to be able to send a SMS to change the alert number in the EEPROM effectively setting up the device so so i can hand it over to another person with out the need to re-flash the device and hard code their number in.
Any help would be appreciated.
I am not running a coin cell battery and therefore the SRAM is not an option at the moment.
