feat: limit TX power to 10dBm for Wio-SX1262 devices - #4
Merged
Conversation
Wio-SX1262 module (Seeed Technology, 201-250230) holds standalone technical conformity certification (技適) in Japan with a certified output of 10dBm, independent of host firmware. Seeed confirmed in writing (2026-07-20) that custom/third-party host firmware and RadioLib usage do not affect the certification, provided hardware, antenna, and RF parameters stay within the certified scope. Devices affected (10dBm, was 13dBm): - XIAO nRF52840 + Wio-SX1262 - XIAO ESP32S3 + Wio-SX1262 - Wio Tracker L1 Pro All other JP devices remain at 13dBm (ARIB STD-T108 limit). Build verified: WioTrackerL1_companion_radio_ble compiles with LORA_TX_POWER=10.
Seeed confirmed in writing (2026-07-20) that Wio-SX1262's standalone technical conformity certification (201-250230) remains valid under custom host firmware, provided hardware/antenna/RF parameters stay within the certified scope. Certified output is 10dBm. Updates both TX power reference tables to reflect the 10dBm limit for Wio-SX1262 devices (XIAO nRF52840/ESP32S3+Wio-SX1262, Wio Tracker L1 Pro), matching the jp-release.yml change in #4.

Summary
Splits the JP release TX power sed into two groups instead of applying
13dBm uniformly to all devices, and documents the certification basis
in README_JP.md.
Wio-SX1262 (Seeed Technology, module-level certification 201-250230)
is certified for 10dBm output only. This certification is independent
of host firmware — Seeed confirmed in writing (2026-07-20) that
custom/open-source firmware and RadioLib do not invalidate it, as long
as the hardware, antenna, and RF parameters (frequency/power) stay
within the certified range.
