I got tired of messing with the module and gave up. now I am back and trying to continue what i was doing before.
I have managed to find and connect to the module, I have also done the loop back test on the module aswell. and seems to work fine up till then. (Loop back test was performed by sending a character from the laptop to the module and shorting the Tx and the Rx so the sent character would be sent back to the computer, and this was a success.)
After the loop back test, i tried sending data from my Mega8 micro controller to the laptop, but this seems to not be working. This data is simply values being sent out from my ADC to USART to the module's Tx pin. I can confirm that the data can be transmitted, as I have tested it with my TTL 232 USB serial connection and i can get the data on my laptop; but when I use the same data with the module I don't get anything on the Laptop. I can confirm the Tx pin is receiving the data, as I can put an Oscilloscope an see data bit on the modules Tx pin. it's just not being transmitted to the laptop.
I have made sure the baud rate is the same.
I have made sure that I am reading the right COM port
I have tried the loop back test various times
The only connections i have made on the module are the 3.3V, GNG, Tx and Rx.
There is something very minute that I am missing and I can't seem to put my finger on it. Could it be the hardware flow control, since I haven't connected those? Am I not sending some sort of start bit?
Any help would greatly be appreciated! and thanks Lee, for replying before.
Cheers.
