Data format 4 (URL)
Lifecycle: Obsolete
The data is packed in Eddystone URL with a base of https://ruu.vi/# and 9 URL-safe base64 characters. Example URL is https://ruu.vi/#BFwaAMjlQ. This is decoded to
0x045c1a00c8e5Offset | Allowed values | Description |
0 | 4 | Data format definition (4 = current sensor readings) |
1 | 0 ... 200 | Humidity (one lsb is 0.5%, e.g. 128 is 64%) |
2 | -127 ... 127, signed | Temperature (MSB is sign, next 7 bits are decimal value) |
3 | 0 ... 0 | Temperature (fraction, 1/100.). Not used, reads always as 0. |
4 - 5 | 0 ... 65535 | Pressure (Most Significant Byte first, value - 50kPa). Rounded to 1 hPa accuracy. |
6 | 0..255 | Random id of tag, only present in format 4. NOTE! because of the URL limitation, only 6 most significant bits will be readable. |
Values supported: -127.99 °C to +127.99 °C in 0.01 °C increments.
Example
Value | Measurement |
0x0000 | 0 °C |
0x8145 | -1.69 °C |
0x0145 | +1.69 °C |
Values supported: 0.0 % to 100 % in 0.5 % increments.
Example
Value | Measurement |
000 | 0% |
128 | 64.0% |
200 | 100.0% |
Values supported: 50000 Pa to 115536 Pa in 1 Pa increments.
Example
Value | Measurement |
00000 | 50000 Pa |
51325 | 101325 Pa (average sea-level pressure) |
65536 | 115536 Pa |
Contains a single random base 64 character used to identify tag.
