I need to add AT commands to specific files into the APM 2.5 to automatically boot up a dronecell or SIM900 at startup
I already had that list of AT commands working thanks to the patience of one great guy here. So now I just need to insert it into the APM 2.5 startup process
So basically all I need to know is which APM 2.5 file I should access and some quick way to modify / save it into the APM 2.5 ? I don"t feel like diving / experimenting/playing around with arduino as it will take me months to understand it.
I understand for instance that I should play with arduplane.pde and system.pde
Your help telling me "just do that and that", or a video link would be highly appreciated.
Thank you very much
You can try adding another arduino board connected to GSM modem and use to control it, like this http://diydrones.com/profiles/blog/show?id=705844%3ABlogPost%3A1819556
Thank you Miguel. Will try to contact Robert... Cheers
