Hardware/Repeaters
If you plan to use a RAK for a repeater (as recommended), please update to the OTAFIX bootloader firmware. Without this fix, if an OTA update fails over BLE the repeater will end up in an unusable state and will require physical intervention.
Download the OTAFIX firmware here: OTAFIX Bootloader UF2 File
Repeaters form the stable backbone of the Ottawa MeshCore network. Below are some example build lists from the community.
Pre-Built
These options come fully assembled; just flash MeshCore and mount them in a high location to expand the mesh. We still recommend upgrading the antenna for best performance. Ideally, use an N-Type connector and upgrade to at least the ALFA AOA-915-5ACM.
NOTE: These pre-built repeaters have not been thoroughly tested by the Ottawa community, but we have seen reports of others using them with great success.
