https://devzone.nordicsemi.com/f/nordic-q-a/37862/measurement-interval-valid-range-descriptorI am trying to add the valid range descriptor to my measurement interval characteristic in the Health Thermometer. This is a necessary step as my measurement interval characteristic is writeable.

You can have a look at the&nbsp;battery_level_char_add() in ble_bas.c where we add&nbsp;the&nbsp;BLE_UUID_REPORT_REF_DESCR descriptor into the battery level characteristic.&nbsp;&nbsp;</p> <p>Please follow what we do in the file to add descriptor.&nbsp;</p><div style="clear:both;"></div>
