I try to run USI ACK module +samd21 demo , but always failed when register it with Alexa app.
I have confirmed with below key point:
1. my Alexa app address is www.amazon.com, app version is 2.2.401007
2. I register the ACK board within 5 minutes after it's power up,
3. my application code example is smartlight, ACK SDK firmware version is SDK3.2, vendor is MTK USI
When I completed scan barcode step, I always get "we failed to receive a response from your device".
So , I have some question about that
do my ACK module need to access the network first when it first power up? ( if yes, how?)
what the "I/O error reading ack " means?
Anyone can help ?
