Configuring a SubGhz Channel
Unlike the 2.4 Ghz band the frequencies used in SubGhz band are not standarized world wide.
Generally speaking the 868 MHz range is used in Europe and the 915 Mhz range is used in North America and Australia.
The Open Elink project supports 5 channels in each of these bands, it is up to the user to configure the system to use a channel which is legal in their country.
The SubGHz radio is an optional module that can be added to an AP to provide SubGhz support.
Currently the OEPL AP firmware only supports the TI CC1101 module connected to an AP based on the ESP-C6 (Yellow AP, Mini AP v3 or Mini AP v4).
If the ESP-C6 detects the CC1101 module the Settings tab on the Open EPaper Link Access Point web page will show the SubGhz channel drop down selection box.
SubGhz is disabled by default.
If your AP has a CC1101 module and SubGhz channel selection is not shown make sure your AP firmware has SubGhz support and that you have cleared your browse's cache.
If the SubGhz channel selection is stil not shown after clearing the cache and refreshing the page then something is wrong.
Select a channel appropriate for your country from the drop down list.
Save the new settings, SubGhz communications are now active and SubGhz tags should be able to connect.
