Hi all,
I am currently working on a project that uses GSM-GPRS to communication to send certain data at certain rate. however, SIM900 is very slow and I have to delay the commands otherwise, it won't be able to keep up with the data stream required.
is there any GSM-GPRS module that supports SPI protocol ?
I think with SPI, I will be able to get better results due to fact that SPI is much faster at rate of 4MHz
regards
