Help I can’t access my Gateway or maybe I bricked it
Note
If you need to restore the device to factory settings but you cannot access it anymore, just reflash the firmware as described below. Newer Gateways have a reset button inside as well.
If your Gateway is not responding anymore, this can have several causes. Usually it’s because a firmware update failed, or the device has lost the WiFi connection. Or you have forgotten the passwords and need to reset the device.
First check the LED on the Gateway.
LED status
No LED
If the LED is off and not blinking, the Gateway may not have (enough) power or the firmware has been corrupted. First unplug it from the EMS bus and the power and replug it. If the Gateway starts blinking, it just needed a hard reboot.
If the LED still remains off, the firmware might be corrupt or the device is bricked.
Note
In some cases for an E32 V2 the board profile may have defaulted to the S32 profile. The ‘symptoms’ are no Ethernet, no EMS bus bus, but the WiFi access point ‘ems-esp’ still works. Log into the ‘ems-esp’ WiFi network, access the web interface of the Gateway. Then go to Settings and set the board profile to E32 V2, save, and reboot. Ethernet will come back alive.
Use the USB flash method to reflash the firmware.
Blinking or solid LED
If the LED is blinking, it has power and is working, but either can’t find the bus or the WiFi network. Check if there is a WiFi network ems-esp. If so, login and see what’s wrong. If your don’t see the ems-esp network, check if you can find the Gateway on your network. If so, try to access the interface via it’s IP address. If you can’t you have to reset the device.
