mDot to multiple AEP gateway

[Micheal Le]

Hi,

I just wonder if it is possible to configure a mDot to send signals by using multiple frequency sub-bands at a time. It looks like that I can only configure a mDot to a specific frequency sub-band. Is this possible to configure to multiple frequency sub-bands?

Thanks

Michael,

It’s true that you can currently only set 1 sub band at a time, but you should be able to achieve this by modifying the channel mask. The Dot library has functions to support this:

        std::vector<uint16_t> getChannelMask();
 
        int32_t setChannelMask(uint8_t offset, uint16_t mask);

The Dot AT firmware uses these functions to implement the +CHM command. It’s documented in the AT command guide.

Here’s the source of the +CHM command.
