I'm currently using VHDL to program the FPGA Spartan 3AN Kit-set. The objective is create a programme to send an SMS to a mobile phone, using the Kit-set via the modem. I'm done with the transmit finite-state-machine (FSM) and started doing for the receive part. However, I'm only required to send an SMS and the only thing to receive is the 'OK', which is send by the modem back to the device, after sending it an AT Command.
The question here is:
- Is receiving the 'OK' from the modem important?
- Can I substitute with delays in between each AT-Commands, assuming the modem is functioning perfectly?
Thanks in advance!
