So, how can I use the sketch to read different sensors?
You example is the first that worked for me so I would like to use it to learn about ble.
I need to connect to uwb devices where i know service uuid and characteristics uuid and formats. What do you suggest?
Being 70 I have no much time remaining to study ;-)). My devices work perfectly with nrf-connect but I need to het the values myself. Thanks a lot.
I try the code and its work, but im still confused about the code, how we know the 4 parameter from sensor in hexa?
temp = (val[0] + val[1] * 256) / ((float)10.0);
moisture = val[7];
light = val[3] + val[4] * 256;
conductivity = val[8] + val[9] * 256;
how we know the temperature in array 0 + 1, and moisture why in array 7
The real time data that comes from the sensor is a single 16 byte ‘string’ which contains temperature, brightness, lux and conductivity values.
Most of these values are too large to hold in a single hex byte, so multiple bytes are used to hold the values, in a least significant/most significant pair of bytes.
More info on the data format can be found here:
