Im using a development board to communicate with the SIm908. the dev board uses the IC SP23238EEA.
My microcontroler is MSP430G2553 and I use MAX232 IC to convert the data to compatible format to be read by the dev board.
The problem is the commands i send from the computer (baud 9600) are read successfully by the computer hyerterminal but not by the SIM908 which is also adjusted to use baud (9600).
I can clearly see the commands on the hypertermnal but when I give the same to the SIM908 it doest activate its GPS.
But it works when I give the commands straight from the computer through its DB9 cable.
Im totally lost. If anyone could help?
