No. It can not be used at the same time.
Dear: 2.0 doesn't use app. but I want to send value to andorid how can i do like AOA1.0
thanks
You can use in the same way. e.g. Android's sample, Yaoadk samples.
I have question with acc.isConnectedHID and acc.isConnected(); I want to use app to receive data with acc.write(msg, 3); and then I want to use HID mouse. How can I conform?
thanks
No.
so aoa1.0 and 2.0 can't be used at the same time?
How to prove it can't be used at the same time?
thanks
Following code is HelloADK + AOA2HID example. https://gist.github.com/YuuichiAkagawa/ae5d28ce6fc108ff9bfe
HID & acc.read() is work. But acc.write() is not work. My Android is Nexus 5@5.0.1 and Nexus 7@4.4.4.
Maybe conflict between HID and Accessory. I don't know how to fix. This is android's problem.
Maybe problem is Data packet error: 5 I use serial monitor appear this error
Usb.cpp 111
//Serial.println( direction, HEX );
if( dataptr != NULL ) { //data stage, if present
rcode = ctrlData( addr, ep, nbytes, dataptr, direction );
}
if( rcode ) { //return error
Serial.print("Data packet error: ");
Serial.println( rcode, HEX );
return( rcode );
}
rcode = ctrlStatus( ep, direction ); //status stage
return( rcode );
I success once with https://gist.github.com/YuuichiAkagawa/ae5d28ce6fc108ff9bfe
and then failed
HID & acc.read() is work. acc.write() is work.
But problem is Data packet error: 5
This image is a captured USB packets. "Control Transfer" is a HID event packet. "OUT txn" is a acc.Write() packet.
Both packets are transferred. But Android App cannot receive "OUT txn" packet.
Again, I don't know how to fix.
It's amazing. I try it sometime is ok. sometime is not ok. This video is prove it is ok. http://goo.gl/ClEpDn The problem maybe Usb.cpp line:148 rcode = outTransfer( addr, ep, nbytes, dataptr, nak_limit ); AndroidAccessory2.cpp line:303 int AndroidAccessory::write(void buff, int len) { usb.outTransfer(1, out, len, (char )buff); return len; }
Because sometime is ok the Serial Montor is appear Data packet error: 5 once. When not ok is appear innumerable Data packet error: 5
error is from hidSendEvent fuction
Dear : titile is my question. I just look your code is acc.hidSendEvent(id, m, sizeof(m));
but the AOA1.0 acc.write fution can use?
thanks a lot
