Dear all,
please help me.
I used PIC 16F877a to send and read SMS via SIM300.
Serial connection:
PIC_TX -> SP3238 -> SIM300_RX
PIC_RX <- SP3238 <- SIM300_TX
Sim300_RTS -> GND
I read/send SMS via SIM300 OK but I send SMS -> Read SMS -> Read SMS(fail)
I don't read SMS again after send SMS. You can help me.
Thanks.
