Hi,
We are currently in the process of getting an custom iAP2 device communicating via USB-C. We have been using the 'EADemo' app as a test app to ensure full function before certification.
Currently, the device completes the authentication and identification successfully. The device appears within the 'EADemo' app, and we are able to select it and see the available protocol. Selecting the protocol sends the EAStartSession command to the accessory and we ACK it.
This is where the issues begin. Attempting to send either a string or hex packet results in nothing being sent. The app does not appear to attempt to send a packet when these are pressed. The 'EADemo' app also does not increment its receive counter when the accessory sends an EA packet, but we do receive the ACK from the device. This indicates the device is receiving the packet, but not processing it in app.
Sending the EASessionStatus from the accessory with a status of okay does not change the behavior. Sending the EASessionStatus packet from the accessory with a status of closed results in the device sending an EAStopSession packet.
The issue does not appear to be with the accessory or the underlying transport layer. Previous attempts to contact MFi support resulted in them referring me to developer support.
Are there any known issues within the 'EADemo' app that we should know about/and or need to fix? Does Apple have any other EA example application? Are there any other publicly avalilbe EA examples that Apple would recommend us trying?
Thanks, Mike
