MeshCore v1.13 plus latest PowerSaving and more features:
1. More Power Saving support [Repeater] :
- CLI: powersaving, powersaving on and powersaving off with detailed messages: meshcore-dev/MeshCore#1687
- PowerSaving for ALL ESP32-based (ESP32S3/C3/C6 and SX1276/sx1262) repeaters: Sleep after 2 minutes from boot. Wakeup on LoRa messages and sleep IMMEDIATELY. Reduced time drift (5 minutes/day to 1 minute/day) for ALL ESP32 repeaters.
- Power Saving for NRF52 at 5.5mA in MeshCore v1.13 is from another contributor: Wakeup on LoRa messages and sleep immediately.
2. More sensor support [Repeater]:
- [Heltec v4] Fixed broken I2C sensors (BME, INA sensors...) for Heltec v4: meshcore-dev/MeshCore#1569
- Automatically selected I2C addresses 0x76 or 0x77 for BME280, BMP280 and BME680. Just plug the sensors to the VCC, GND, SDA and SCL.
- Added i2c probe for sensors to start only in-use sensors: meshcore-dev/MeshCore#1282
3. Hot fixes [Repeater/Companion]:
- [RAK4631 / Heltec T114 / Xiao NRF52] Reduced voltage boot lock from 3.3v to 1.8v in NRF52 power management. This is useful for devices with non-Lipo batteries: meshcore-dev/MeshCore#1629
- Automatically restart after flash for Heltec v4 (CDC support): meshcore-dev/MeshCore#1335
4. More variant support [Repeater/Companion]
- Xiao S3 (non-Wio) and Wio SX1262 (Initial support): SDA=D6, SCL=D7
- Xiao C3 (Latest support): SDA=D6, SCL=D7
- Xiao C6 (Latest support): SDA=D6, SCL=D7
