I just bought a Marshall Code100C from the Sweetwater sale.
Anyways I have 2 older Amdroid phone and NONE can get the Code Gateway App.
But my Newest LG Android phone can download the Marshall Gateway App and install it.
Problem is when I turn on the Code 100C and Turn on The Gateway App on my Android phone
it does NOT find the Marshall 100C and I downloaded the Newest Firmware for the Marshall 100C.
What can be my problem?.Thanks allllll....JT
Thank you for getting in contact, can you confirm you connection process, are you activating the Bluetooth on the amp and also connecting in the phones bluetooth settings before opening the app.
