    BLE Thermometer Higher Resolution

    rhamilton_1615346

      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:

         
            
      • CY8C4247LQI-BL483 module
      •     
      • CY8CKIT-042-BLE pioneer board 
      •     
      • PSoC Creator 3.3
      •    
         

      I attached the design files from AN91184 and the configurations being used on the thermistor.
