https://devzone.nordicsemi.com/f/nordic-q-a/2550/s120-how-to-modify-a-value-in-an-s110Im trying to have the s120 modify the value like I would in Do a Read all records operation in the Glucose example. I cannot figure out what function would enable me to do this. Basically my goal is to have the s120 send a number for example &quot;10&quot; to theen-USTelligent Community 13Tue, 27 May 2014 18:19:39 GMThttps://devzone.nordicsemi.com/thread/10150?ContentTypeID=1Tue, 27 May 2014 18:19:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dcb0f0d9-71fb-4adb-9833-2abca25ec159BrettD<p>I was looking for a way to have the s120 change the battery level on the s110 device. Currently I have modified the battery service from the ble_app_hrs to be a writable value. When I connect with the nordic master control I can change the battery level on the s110. I would like to achieve this using the s120 device to change the battery level on the s110. I have found the definition for a case BLE_GATTC_EVT_WRITE_RSP in ble_bas_c in the S120 ble_app_hrs_c. I have been trying to write the code to modify the value in the s110. Any help or example code would be greatly appreciated I added some extra code to the original question</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/10149?ContentTypeID=1Tue, 27 May 2014 08:31:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:452b3a74-f09f-4246-8899-bc48fe3a7e05FormerMember<p>There are two ways (or possibly more) to get the battery level from S110 to S120:</p> <ul> <li>Notification: The S110 uses notification to update the battery level</li> <li>Read: The S120 device reads the battery level value from the S110 device.</li> </ul><div style="clear:both;"></div>
