boards/tracker-t1000-e.json set the application's usb_product to
"T1000-E-BOOT". PlatformIO's nordicnrf52 builder turns that key into
-DUSB_PRODUCT, which lands in the USB device descriptor, so a running
node enumerates as "T1000-E-BOOT" while the Seeed bootloader enumerates
as "T1000-E". The firmware that is not the bootloader is the one wearing
the bootloader's name.
That misidentification is load-bearing in the web flasher.
flasher.meshcore.io calls navigator.serial.requestPort() with no filters,
so the row label in the browser's port chooser -- which the browser builds
from the USB iProduct string -- is the only signal the user has. The nRF52
flow prompts twice, once for the 1200-baud DFU touch and again for the
flash itself, with no re-enumeration watcher in between, and at that
second prompt the two candidate rows read:
T1000-E-BOOT (239a:8029) <- the application
T1000-E (2886:0057) <- the actual bootloader
which is backwards at the moment the user has to tell them apart.
The same define is also the Adafruit core's CFG_DEFAULT_NAME, so it is
what a companion advertises over BLE whenever the intended name is too
long for the GAP device-name attribute and setName() silently fails
(#1769). The string is user-visible over Bluetooth as well.
Name the application after the firmware it runs rather than after the
board. This deliberately differs from the hardware-name convention in the
other nRF52 board files ("WisCore RAK4631 Board", "Seeed Wio Tracker L1")
because the string's job here is to distinguish the running application
from a bootloader that will never claim to be MeshCore; "Seeed T1000-E"
would sit one word away from the bootloader's "T1000-E".
Upload and flashing are unaffected -- PlatformIO's port autodetect matches
on hwids (VID:PID), not on this string. On Linux the /dev/serial/by-id
symlink does change, from usb-Seeed_Studio_T1000-E-BOOT_<serial>-if00 to
usb-Seeed_Studio_MeshCore_T1000-E_<serial>-if00, so anything pinned to the
old path needs updating.
