i working new ble api of android 4.3. able scan, connect, discover characteristics e.t.c le device.
in case of reading characteristic value, characteristics, getting responses , others getting no response.// guessing it's device fault
the problem write operation. device have 2 characteristic write property. when trying write them 2 cases occurring in random -
- onwritecharacteristic not being called , value not changed device.
- onwritecharacteristic being called success status despite fact writetype set write_type_no_response, still no value change.
some non-4.3 apps changing characteristic values. not device fault guess.
any insight or gratefully appreciated.
edit 1: here on snippet of log, when trying write characteristic device.
