RUI3 v4.3.0 Firmware Update: FSK Testing Support & Bug Fixes
What's New in RUI3 v4.3.0
- Changed FSK mode testing support for six AT commands.
- Fixed device, connectivity, and sleep mode issues.
- Fixed LoRa certification testing failures.
- Optimized the STM32 I2C driver.
NOTE
Supported Hardware:
- STM32: RAK3172, RAK3172-SiP, RAK3172LP-SiP, RAK3172-T, RAK11160
- nrf52: RAK4631, RAK3401
- Apollo3: RAK11720
Changed
- Changed FSK mode testing support for the following AT commands:
AT+TCONFAT+TTXAT+TRXAT+TRSSIAT+TTHAT+TRTH
Fixed
| Daily Build No. / Bug No. | Description |

| — | Fixed uplink timer failures during LoRa certification testing. |
| — | Fixed device class switching failures during LoRa certification testing. |
| — | Optimized the I2C driver for STM32 platforms. |
Who Should Upgrade to This Firmware Version
This update is most relevant for:
- Developers testing FSK mode using the supported AT commands.
- RAK3172-CN users experiencing LoRaWAN join failures.
- RAK4630 users encountering LoRaWAN join failures in the EU868 region or sleep mode issues during LoRa P2P operation.
- RAK11720 users experiencing sleep mode issues.
- RAK3172 and RAK3172-F users affected by device unresponsiveness or hangs.
- Developers conducting LoRa certification testing.
- STM32-based projects requiring improved I2C driver optimization.
