Renpho R-A012 Scale Support Debug Info

[FoleyPhotonics]

Scale name
Renpho R-A012

To support a new scale it is necessary to gather some information.

Step 1: Read the general reverse engineer process

• I have read the how to reverse engineer a Bluetooth 4.x wiki entry

Step 2: Acquiring some Bluetooth traffic
Attach 3 log files with the corresponding true values, read here for further information.

1. Bluetooth HCI Snoop log file
   user settings in the vendors app:

Sex: male, Height: 179cm, Age: 42, Activity Level: Sedentary

measured true values in the vendors app for the 1. HCI Snoop log file:

Weight: 81.50kg, Date: 23 Jan 2025 10:54:01 am, BMI: 25.7, Body Fat: 26.5%/21.60KG, Subcutaneous Fat: 23.6%, Skeletal Muscle: 47.4%/38.63kg, Metabolic Age: 43, Fat-Free Mass: 59.90kg, Visceral Fat: 9, Body Water: 53.1%/43.28kg, Muscle Mass: 69.8%/56.89kg, Bone Mass:3.7%/3.01kg, Protein: 16.8%/13.69kg, BMR: 1670kcal.

2. Bluetooth HCI Snoop log file
   user settings in the vendors app:

Sex: male, Height: 179cm, Age: 42, Activity Level: Sedentary

measured true values in the vendors app for the 2. HCI Snoop log file:

Weight: 87.00kg, Date: 23 Jan 2025 10:54:28 am, BMI: 27.5, Body Fat: 28.5%/24.80KG, Subcutaneous Fat: 25.2%, Skeletal Muscle: 46.0%/40.02kg, Metabolic Age: 45, Fat-Free Mass: 62.21kg, Visceral Fat: 10, Body Water: 51.6%/44.89kg, Muscle Mass: 67.9%/59.07kg, Bone Mass:3.6%/3.14kg, Protein: 16.3%/14.18kg, BMR: 1726kcal.

Contained in the HCI Snoop log file along with the first measurement.

Step 3: Discover Bluetooth services and characteristic

Hi, my name is joel david, I'd like to contribute to this issue. I'll gather the necessary Bluetooth traffic and debug information to support the Renpho R-A012 scale.
