hi dear friends
i am trying to design a wireless data logger device based on a simcom sim900a gsm/gprs modem.
& eliminating external mcu is very pleasure to me ,then sim900's mcu will do process.
as you know simcom used arm926ej arm 9 mcu on sim900 which is absolutely enough for many embedded applications.
simcom publish a pdf as "sim900 embedded at applications notes" for reference that i have a bit confused of undrestanding its mind.
is there any body here do this past or has any experiences in this?
i think we only write tasks for its real time os ?is it true?
or for example with at+command i can connect with http to a server on internet & based on get/post requests send & receives datas via sim900's usart port ? but i dont know how can send/received this datas when im not using external mcu(transieve from core mcu to my application)
can any one clear me or give me some simple examples?
best regards
