 okay so when you first turn on the SD21 PCNFC software and then you connect using this SD25R311B discovery board you should see and if it scan the tag here you and get a UID you should see this LED pattern right here now on the discovery board at the moment it boots up you see these three basically three button and you choose that button so that you'll be in this configuration to do the picture transfer demo okay so go ahead and launch your SD25 PCNFC application the PC application and when that happened you should see the disco connected mean that you are successfully connected to the SD25R311B discovery board and up here you should see the UID of the SD25DV discovery board the red board now once you boot it up you should see three icon and you should choose the FTM the center using the touchscreen and it would say on it ready to start demo so when that happened you can go to fast transfer mode up here and click on picture transfer so here you have a choice of downloading or uploading content from the tag in this use case I was thinking if you would want to download parameters configuration data onto your device via RFID or NFC using the reader so you would want to do a pick pick a pictures to to download because it's just a binary data so it's an example now here it kind of give you that same thing I was telling you earlier when you boot up the board on the discovery board you click you tap on this FTM button and you should see the screen ready to start demo now you will start the demo now you see this fast mode button here I leave that unchecked because it seems that the logic seems to be like going around for this application it's actually when it's not click tick it's actually in fast mode when it's tick it's actually in a standard ISO 156 93 mode which is like 26 kbps now the fast mode commands can go up to 53 kbps okay so now let's click start and and on your board you should see a progress bar and the amount of data being transferred it's around 100 k bytes as it said on the discovery board and as you can see we almost halfway through and it takes about 20 odd seconds so when you look at this performance it's not super fast but for a lot of configuration data it doesn't have to be 100 k bytes it can be pretty quick if you're not sending 100 k bytes so here we're completed at around 42 seconds transferring about 100 k bytes of data if you click you should see the CRC values on the top and the duration on the discovery board which is very equivalent to what you see here on the PC screen then then you click tap the screen again on the discovery board to display the image and you might see just a partial image because the screen is much smaller than the actual pixel data okay that that's pretty much in a nutshell what you what you can do when you transfer data back and forth between the SD 25 DV discovery board and the SD 25R in 11b discovery board thank you
