-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.
Removed the call to Bluefruit.ScanResponse.addName() in startAdv(), as it was preventing BLE from reliably restarting advertising after a disconnect.
Hypothesis: adding the device name to the scan response exceeds internal buffer limits or causes a conflict with advertising timing, leading to the BLE stack silently failing to re-advertise.
Tested successfully (on T-1000) without this line, advertising now resumes correctly after disconnection (on Iphone)
