I have started putting together my greenhouse project. I am currently running a tempreture and soil humidity sensors throughout my greenhouse in my allotment. I am trying to find a way where I can use my GSM900A to transmit data to and from my allotment either to a local server at home or directly to the blynk app.
My allotment doesnt have any power or wifi to connect so I have managed to install power via solar and hooking up some batteries but I am struggling to find any code related to sending and receiving data via GSM900a.
Managed to use the example from Blynk and add it to my script. Had a bit of jip with the baud rate I have overcomed that. Onwards and upwards for this project! Now need to work out whay my GPRS details are from GiffGaff
@Rob.b Cannot for love of me work out why my code wont run when selecting the SIM900. I can export on the SIM800 but not on SIM900. Tried to add the .h file for it but not getting any luck! Can you have a little look for me please
This is a great tool for making sure your gsm module is working.
I used it to make sure everything was working correctly before I progressed to the Blynk side of things.
