I'm having an issue trying to increase the resolution (decimals) of the temperature received over a Bluetooth LE Health Thermometer Service. Im using the example from AN91184, and the temperature can only be received as XX.00 deg.
To start, I tried changing the Thermistor configurations to have 0.1 deg for calculation resolution (instead of 0.5), and I also changed the max/min/mid temperature and resistance based off of recommendations from AN66477. It seems as though the ADC is properly calculating the temperature, but the HTS is not configured to send a high enough resolution.
I'm also using the following equip/materials:
I attached the design files from AN91184 and the configurations being used on the thermistor.
HTS is specified by Bluetooth SIG as a standard service. This cannot be altered. You may custom service if you want to send a different kind of data.
