    I am in the UK but developing a product for the North American market.

    Since version 4.0.0 of firmware, is it simply a case of changing the default frequency with AT+DFREQ to change a module from the NA915 version to the EU868?

    For xDot the global plan provided with 4.1.2 would be needed to change the channel plan through commands only.

    Other wise the channel plan specific firmware must be used, i.e. load US915 for use in NA.

    OK, thanks you.

    So if I load ‘xdot-firmware-4.1.4-GLOBAL-mbed-os-6.8.0.bin’

    Could you please tell me which AT commands I need to use to switch between EU868 and US915?
