Crash when reading battery level
I am accessing a MetaWear sensor from an iOS app. I am experiencing intermittant crashes when I ask for the battery life. The crash is a SIGSERV at the following line of code: -[MBLMetaWear peripheral:didUpdateValueForCharacteristic:error:] (MBLMetaWear.m:1531)
Is there other state I should be checking before I ask for the battery life?
