ANT Forum

Hello,

I try to develop an application with ANT-FS and I have 1 MCU ANT which connected to a MCU Atmel and 1 USB ANT+. How can I visualize how my MCU ANT transfer data to USB ANT+? Does ANTware II works with ANT-FS? Can I configure my USB ANT+ to receive data from my MCU ANT via ANT-FS? If not, is there any software allows to do this ?

Another question about ANT-FS. In general, to transfer data, ANT-FS must use Burst transfer (sorry if I am wrong). So, it use the same method of ANT normal, but it allows us to work directly with the files existed in EEPROM (ex: creat file, delete file ....) and it is more secure (authentification). Am I right about that or is there something I miss about ANT-FS?

Second,
Thanks very much for your helps      

From your other post it seems you are using the integrated ANT-FS client feature of the CC257x part. In order to receive the data, you would need to use the ANT-FS PC host with a USB stick. You can download this software tool, along with its user guide, here

You may also find useful the "Integrated ANT-FS Reference Design", available here

This tool would let you connect a C7 module to the PC (through an USB interface board), and explore its functionality through a PC application. The worked example in the manual for this tool is a good starting point.

ANT-FS uses bursting, along with a defined command/response structure to achieve reliable file transfers. I would recommend having a look at the first few sections of the "ANT-FS Technology Specification" document for more details about the messaging involved in ANT-FS. This messaging is already implemented for you in the CC257x (i.e., you don't need to manually format the responses in your code), but the underlying mechanism is the same. The C7 also implements a file system, by interfacing directly to the EEPROM, and allows you to use AES-128 for encrypting files.
