If ACK was connected to a WiFi AP once, ACK goes to connect with the same AP each time.
Could you tell us how to change WiFi AP.
I am having the same problem. I cannot connect to the device anymore via Alexa app either. Is there a way to reset/clear the registration information using the Java utility? I have already updated to the latest firmware and that didn't help.
I do not see this CLI command listed anywhere in the CLI utility reference :
Update (also posted to another similar thread)...
Ok, I have finally solved my problem by connecting a USB cable to the debug port on the ACK shield board (with the Arduino still connected).
This port enumerated as serial comport #11 on my PC, but yours may differ. The trickiest part was figuring out the baud rate. Turns out it is 115200. I suppose I could've looked through the sample code or the libraries to figure that out, but really this should be documented somewhere on the ACK developer site in the specs.
Anyway, once I figured that out, I used the command to re-register, which is "devkit start_registration user_guided". Then continue with normal registration in the Alexa app. If that doesn't work, there is also a cmd to clear out the registration info which should achieve the same result in a few extra steps. Also there appears to be entire menu of debug port items that look pretty useful but are not documented anywhere (at least that I could find).
version - Prints version information
wifi_network - Wi-Fi network management operations
devkit - Module control and state operations
crypto - Cryptography-related operations
simple_setup - Wi-Fi Simple Setup operations
otw - Over-the-wire firmware update operations
logging - Logging operations
reboot - Reboots the module
It would be really nice if you guys could document this somewhere on the ACK developer website. I didn't find it by a browser search and there is really no reason for it not to be there. I was able to update the FW using the Java utility. That, on the other hand, seems to be fairly well documented. Hope that helps the others.
