hi, I want to connect the Fastrack Supreme to a microcontroller ATMEGA16. Please, somebody who help to develop an aplicattion on the Fastrack Supreme to get data from the Microcontroller, and then, send those data via GPRS to a server, which have a public IP. Another question: It is necesary the use of CTS, RTS(Handshake) between comunication of the Fastrack and ATMEGA16(microcontroller)? Kind regards. ---

> [@poroncom](#): > > Please, somebody who help to develop an aplicattion on the Fastrack Supreme to get data from the Microcontroller, and then, send those data via GPRS to a server, which have a public IP. You have a couple of choices for the physical connection: 1. A standard RS232 connection between the ATMEGA’s UART and UART1 or UART2 on the Fastrack; 2. Use the I2C, SPI, or GPIO on the plug-in IO card. And a few choices about the higher-level operation: 1. Just use the Fastrack as a dumb modem, and do everything via standard AT commands; 2. Use WIPSoft to take advantage of the IP stack within the Fastrack; 3. Create an Open-AT application within the Fastrack to manage all the GSM/GPRS stuff, and leave the ATMEGA to do just the stuff that the Fastrack can’t You should really be talking to your Wavecom distributor to discuss these (or other) options… > [@](#): > > Another question: It is necesary the use of CTS, RTS(Handshake) between comunication of the Fastrack and ATMEGA16(microcontroller)?

I choose the first option A standard RS232 connection between the ATMEGA’s UART and UART1 or UART2 on the Fastrack; I have a problem, Lamentably, I am new in the management of this device, I have just bought a fastrack supreme… Please help me to make an application in the fastrack , I need this application because I am doing a project school wich consist on the next: A microcontroller (ATMEGA16) is running an application and at the same time it sends 3 bytes of information every 30 seconds to the fastrack , then this devide should encapsulate this information for can send this data via GPRS to a server which has a Public IP. Also I need that the fastrack send one character(A,B,C) every 5 minutes In agreement an hour (for example if the time is between 5 to 11 am , the fastrack will send the character “A” ),this characters are sent to the microcontroller(ATMEGA16) and finally I need receive data on the fastrack from a PC-application which is locate back to the server, and this data(1 byte) also sent to microcontroller. PD. I attached a diagram of my application. It can help you to understand the porpouse of the project. I hope you excuse me for my english ,because I from Ecuador -South America… Kind Regards… ---

Ok, thanks a lot for your help. I’m going to read the guides, to can create the aplication. If I have a problem, can I write you? so you could help me. KInd Regards.
