Milestone 10: serve pager units sold with SX1262 instead of LR1121.
Same board JSON, same variant dir, same NSS/RESET/BUSY/DIO1/SCLK/MISO/
MOSI pins as the LR1121 env -- confirmed against trail-mate's own
working SX1262 pager reference that it's the same physical radio slot,
just a different chip populated. RADIO_CLASS/WRAPPER_CLASS swap to the
core fork's CustomSX1262/CustomSX1262Wrapper, the exact same generic
classes the T-Deck already uses, so radio_init() just calls
radio.std_init(nullptr) -- no new radio C++ code needed, only build
flags.
TCXO voltage and the DIO2-as-RF-switch setting are NOT copied from the
T-Deck wholesale: trail-mate's reference for this exact PCB uses
RadioLib's own 1.6V TCXO default with no override, so
SX126X_DIO3_TCXO_VOLTAGE is left undefined here too (std_init() already
retries at 0.0f on an SPI-cmd failure). SX126X_DIO2_AS_RF_SWITCH=true
and SX126X_CURRENT_LIMIT=140 ARE carried over from the T-Deck, but
because both are tied to the shared LORA_TX_POWER=22 target (RadioLib's
default 60mA current limit silently caps real TX power below 22dBm on
any board, not something T-Deck-specific), not board-specific analog
circuitry.
Also fixes a real bug found compiling this for the first time:
target.h only ever included the LR1121 wrapper (vendored locally in
this variant dir), never the core lib's CustomSX1262Wrapper -- unlike
T-Deck/Heltec V4's own target.h, which already include it. RADIO_CLASS/
WRAPPER_CLASS resolved to nothing and every radio_driver.* call site in
MyMesh.cpp failed to compile.
Hardware-verified: flashed a real SX1262 unit via the documented
out-of-box recipe (full erase + merged image), boot log confirmed
radio init succeeded alongside the rest of the board, and a live
mesh test confirmed send/receive on the public channel, a custom
channel, and DM.
