 Hi!

I have just purchased a Siemens TC45 GPRS-module. Now I need to decode audio from the audio interface and send it to a server over GPRS. Is this possible with the TC45 alone, or do I have to buy some additional hardware? I am planning to write my software in J2ME. I have tried to find code examples for this but without any luck. As you can see I am novice to this and J2ME, so any help will be highly appreciated. What should my next step be?

You will need additional hardware, a codec or similar, and connect it to the serial interface (ASC1).  There is no direct access to the audio data within the JAva environment of the TC45.

I am only interested in sending audio from 0 Hz to 3000Hz and record around 30 seconds. It is not important that the audio is sent fast. I had an idea to just read the raw data from the audio interface on the TC45, apply some basic coding, Huffman for example, and then send it to a receiving computer using GPRS. Do you still recommend me to purchase the MTC45T?

I am very grateful for your earlier answer. Thank you.
