📱 Connecting to the device

BLE device name: STATOTEST_GEOSNAKE-[address]

• Example: STATOTEST_GEOSNAKE-1 (for address 1)
• Example: STATOTEST_GEOSNAKE-10 (for address 10)

Security details:

• PIN code: 123456
• Encryption: Yes

🔍 Return values

The ADXL355 measurement contains:

• Sample count - how many values were measured
• XYZ aggregation - minimum, maximum, average for each axis in g
• Temperature - the current sensor temperature in °C
• Angles - angle X, Y, Z calculated from the acceleration

Error messages:

"Invalid address"     - Invalid address (out of the 1-255 range)
"Invalid baudrate"    - Unsupported speed
"Invalid points"      - Invalid sample count (out of 24-1024)
"Address set OK"      - Address set successfully
"Baudrate set OK"     - Speed set successfully
"ADXL355 points set OK" - Sample count set successfully

⚠️ Important notes

1. The wifi_on command causes a restart of the device
2. A measurement can take several seconds depending on the number of samples
3. Addresses 1-255 are valid for Modbus communication
4. Setting changes are saved to the flash memory and survive a restart
5. Only one task can run at a time (ADXL355 or MLX90393)
