This commit introduces several improvements to the SerialBridge helper:
- Adds support for the nRF52 platform by implementing the `setPins` configuration.
- Corrects the type cast for the RP2040 platform from `HardwareSerial` to `SerialUART`.
- Refactors packet deserialization to use a new `Packet::readFrom()` method instead of a direct `memcpy`, improving encapsulation.
- Updates the packet length validation to use the more appropriate `MAX_TRANS_UNIT` constant.
Implement a "seen packets" table to track packets that have already been processed by the serial bridge.
This prevents packets from being re-transmitted over the serial link if they have already been seen, and it stops inbound packets from serial from being re-injected into the mesh if they are duplicates.
Duplicate inbound packets are now freed to prevent memory leaks.
This commit refactors the serial bridge functionality out of the `simple_repeater` example and into a more reusable, object-oriented structure.
An `AbstractBridge` interface has been introduced, along with a concrete `SerialBridge` implementation. This encapsulates all the logic for packet framing, checksum calculation, and serial communication, cleaning up the main example file significantly.
The `simple_repeater` example now instantiates and uses the `SerialBridge` class, resulting in better separation of concerns and improved code organization.
Adds a new variant 'ikoka_stick_nrf' and associated support files. This is
based on the Xiao nRF54 code with pin numbers and functions changed to suit the
differences in hardware between the WIO SX1262 board and the Ikoka Stick.
Sets the default LoRa transmit power to 9dBm to avoid burning up the frontend
in Ikoka Sticks equipped with the Ebyte 33dBm S22 module on first boot.
Adds support for an SSD1306 display connected to the display header. Note the
display pinout is the same as the RAK4631 display header so make sure to use a
display wired accordingly (aliexpress etc. SSD1306s typically have Vcc & GND
reversed from what this board expects).
Adds support for display rotation to SSD1306Display via a platformIO define.
This support was added following the same paradigms found elsewhere in the code
for rotating a display.
