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.
-Added RAK_4631 define back
-Added includes for common RAK sensors that are currently supported in ESM
-Set global variables to static
-Reduced delay time within the RAK gps init sequence
Changes to migrate sensor code to the ESM.
Added a separate GPS init sequence for the RAK that scans I2C and Serial1 on the various sockets of the various base boards to find the RAK12500. (and soon the RAK12501)
Removed the GPS specific envs from platformio.ini and enabled GPS for all envs.
Verified working with RAK12500 on RAK19007 sockets A and D, as well as RAK19003.
* Sensor, anon_req now just for admin login (guest password now unused)
* special CLI command, "setperm {pubkey-hex} {permissions-int16}" for admin(s) to manage user access (permissions 0 = remove)
Replaced use of `restartOnDisconnect(true)` with explicit (existing) manual re-advertising logic.
This avoids Bluetooth stack instability caused by overlapping advertising state,
Changes:
- Added explicit `Bluefruit.Advertising.stop()` and data clears in `startAdv()`
- Disabled automatic restart with `restartOnDisconnect(false)`
- Re-advertising now fully handled in `checkRecvFrame()` loop
Tested on: iPhone, Android, Windows, and Chrome – confirmed stable reconnects and name visibility.
