Important changes to repositories hosted on mbed.com
Mbed hosted mercurial repositories are deprecated and are due to be permanently deleted in July 2026.
To keep a copy of this software download the repository Zip archive or clone locally using Mercurial.
It is also possible to export all your personal repositories from the account settings page.
The channel plans in this library can be used as starting points for new channel plans and used as a reference for implementation.
Information
To use source version of a channel plan, first remove the Channel Plans folder from libmDot-Custom library.
Not all plans are complete to LoRaWAN specifications.
AS923 and KR920 have the default channels defined and can accept in channels in the Join Accept message or from New Channel MAC commands.
Channel Set must match those expected by the network server in order for ADR to work
AS923 regional settings can be adjusted by the network server using Tx Param Setup MAC command to set max EIRP and dwell time for uplinks.
