Tom Fifield	a3e6f16378	Introduce non-linear TX_GAIN_LORA (#8107) ... * Introduce non-linear TX_GAIN_LORA Previously, our TX_GAIN_LORA setting was a single number, intended to represent the signal gain going through a power amp (plus or minus antenna, attenuator, and other parts of the RF chain). It turns out the relationship between the input power (i.e. from an SX1262) and total output power is often non-linear. While we fudged a 1dBm difference here and there with existing chips, the Heltec v4 has a 5dBm difference in gain depending on which end of the input power (and frequency) you are at. To allow people to run their Heltec v4 at max power when legal, and future proof our code, this patch introduced an optional array-based TX_GAIN_LORA. Define NUM_PA_POINTS and set TX_GAIN_LORA to gain values for a given input power in 1dBm increments, and all will work. For linear systems, just continue to define TX_GAIN_LORA as a number. Fixes https://github.com/meshtastic/firmware/issues/8070 * Remove temporary power limit on heltec v4 * Add function RadioLibInterface::checkOutputPower * Ensure SX126x reaches minimum supported power. * Keep it simple, instead.	2025-09-30 08:20:39 +10:00
