Orange RX OpenLRSng 433MHz TX Module and Receiver Combo w/Bluetooth

The all new Orange OpenLRSng is an open source transmitter module and receiver combo pack that can be programmed to use your choice of protocol and any channel in the 433MHz range. It is a fully user-customizable RF transmitter system that can even be programmed to utilize additional features such as telemetry, operative remote control via stics (cPPM ready) and mission control.

The module is designed for using with APM flight control software and is equipped with Bluetooth technology so the user can connect it to a tablet, smartphone or PC. All telemetry data, mission planning and flight modes will be available in APM Mission Planner on PC or Droid Planner or similar app's for Android devices. Thanks to the bluetooth function, no additional leads are required to setup / program the transmitter module.
 
The Orange OpenLRSng is an extremely versatile system and is perfect for custom projects,
It utilizes a 1000mW RFM22B RF unit and Atmega328 processor with Arduino Bootloader
allowing you to upload pre-written codes or write your own to suit your transmitter needs.
 
The default code utilizes 3 channel frequency hopping spread spectrum technology. If you would like to use a different protocol, you can write your own hopping codes or simply download one of the many pre-written OpenLRS code sets already available.

Features:
• 3.3v FTDI support for easy programming
• Bluetooth for telemetry, mission control and mode change
• 16Mhz Atmega328 processor with Arduino Pro Mini compatible bootloader.
• U.F.L connector between PCB and antenna
• Audible warning buzzer
• RFM22B transceiver unit including Si4432 chip with configurable 0-1000mW output
• Can be used with a bi-directional amplifier for improved range
• Frequency hopping spread spectrum capability (FHSS)
• MAVLink protocol framing and status reporting
• Configurable duty cycle
• Supports for LBT and AFA
• Adaptive time division multiplexing (TDM)
• Built in error correcting code (can correct up to 25% data bit errors)
• Open source firmware
• AT commands for radio configuration
• RT commands for remote radio configuration
• Adaptive flow control when used with APM
• Based on the HopeRF HM-TRP radio module, featuring a SiLabs Si1000 RF microcontroller

The 6v pin is grounded on these modules, which is a big No-No for an old JR/Graupner radio as it will fry the 6v regulator. In order to avoid such nuisance either "cut the trace" on the module, or cut the 6v output wire on the radio.
See https://www.rcgroups.com/forums/showpost.php?p=27102426&postcount=1 for the detailed pinout.

The combo comes with openlrsng 'gitsly', i.e with specific mavlink support. As a result the bluetooth module is setup for 57600bps. In order to use regular openlrsng and chrome configurator one should adjust the BT module for 115200bps (or hack the code so as to modify serial.begin(115200) in TX.h file)
The BT module is basicaly an HC-06 module that can be programed with a terminal such as the arduino IDE serial monitor. Just connect the module to an FTDI adapter (do not forget to reverse the rx/tx pins). Power the BT module, do not bind any BT device as it stays in programming mode while not paired (led should keep blinking). Send "AT" (without quotes) module should reply "OK" then "AT+BAUD8" response should be "OK115200".
NOTE : Do not use putty as the module is expecting the full AT command to be written as a whole not on a character per character basis.
The receiver cannot be flashed with an FTDI adapter, you will need an USBASP adapter.
The transmitter module is limited to ~500mw in order not to max-out the power regulator of the radio. I've fried quite a few 0.5A fuses while "binding". The voltage regulator of the module is noisy which somehow confuse the transmitter. I am considering adding either a DC filter or a dedicated UBEC in the transmitter case.

Great quality built, Flashed RX with 3.8.8 firmware using Arduino and USBASP 3.3v. It is working perfect after that. Bluetooth a little hard to configure but it works. Still to do a range test, i have no doubts it will perform ok. I am willing to see how 1w telemetry works. Good job Hobbyking.
