Merge Risk: 🟠 High · up to The new recovery workflow can erase bootloader code while attempting to preserve manufacturing data, potentially leaving a physical device unusable. This must be corrected before the script is used; the timeout and documentation issues should also be addressed. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Pull request overview
This PR reorganizes repository documentation and adds OSTC4 service and bootloader recovery tooling.
Changes:
- Documents repository, tools, scripts, and documentation layouts.
- Adds RFCOMM and Bluetooth-name handling.
- Adds bootloader flashing with manufacturing-data preservation.
- Updates ignore rules.
Unresolved flashing, path-resolution, and service recovery issues require changes before approval.

read(1)consumes the command echo, but the application protocol emits0x82first and only then returns the0x4Cprompt (seeDiscovery/Src/tComm.c:699-772). The application path is therefore interpreted as the bootloader path,application_restartedstays false, and the reconnect at lines 566-567 never runs; a device coming from the application will not receive the forced-name command in this invocation. Read and classify the echo plus the following prompt before deciding whether to reconnect.
scripts/ostc4_service.py:563- On the
needs_reinit_for_bt_namerecovery path, this new call raisesCommand 0x82 was not acknowledged...when the device drops the connection, but the handler below still searches only for"not echoed". That makes the reconnect-and-retry block unreachable for this acknowledgement path, so the operation exits instead of reconnecting.

In `@scripts/flash_bootloader_preserve_mfg.sh`:
- Line 95: Update the flashing flow around the st-flash write command to
preserve Sector 2: read the complete 16-KiB sector containing MFG_ADDR, patch
only the manufacturing block, write the full patched sector back, and verify the
complete sector afterward. Keep the existing manufacturing data behavior while
ensuring unrelated Sector 2 bytes, including bootloader code, remain unchanged.
In `@scripts/ostc4_service.py`:
- Line 105: Restore args.timeout to its configured value in
open_service_connection after retry initialization and before returning the
connection, while preserving the shortened timeout used by open_connection when
attempts > 1. Ensure the returned RFCOMMConnection or serial.Serial uses the
original timeout for later set_bluetooth_name reads.
In `@scripts/README.md`:
- Line 5: Update the command examples in the README so they run from the
repository root by including the scripts directory in each referenced path,
while preserving the existing usage and safety warnings.

The recovery script has a critical cross-platform data-loss risk, and Bluetooth-name handling has a moderate command-retry defect.

scripts/ostc4_service.py:403
- When the application build receives 0x82, it first echoes the command and then sends the 0x4C/0x4D prompt (
Discovery/Src/tComm.c:687-700,764-773). This read consumes only the 0x82 echo, so the code treats the application response as the bootloader acknowledgement, never returnsTrue, and skips the reconnect/reissue path at lines 573-576. As a result, invoking--set-bluetooth-namewhile the application is running does not send the command after the device reboots into the bootloader; read and classify the complete application response while retaining the one-byte bootloader case.
