hi I need a to transform a code used for wifi connection (esp8266) to GSM sim800l connection (using Arduino nano). In code are two sensors, one for humidity and temperature and another one for weight. the sistem should work like: send SMS with,,0'' --> receive message with the data's. send message with ,,1'' --> receive message from 1 hour to 1 hour from sensors. Sent message with ,,2'' all the above commands to be cancelled. The code must include multiple APN's (to allow you to change the SIM card without rewritting the code)
I'm experienced in everything related to the Embedded System and GSM/Zigbee/nRF/Wifi interfacing.
I have designed, programmed and implemented many projects like yours and I can add conditions if you like for sending the SMS for example in case of receiving request SMS.
Send me message if you want to hire me.
