Bluetooh GATTCCharacteristic Notification
import machine, ubinascii, utime from network import Bluetooth from BleScan import BleScan def handleNotification(bt_o): print('notification handler') myble = Bluetooth() con = myble.connect(ble_addr) srv = con.services() ch = srv.characteristics() ch.callback(trigger = Bluetooth.CHAR_NOTIFY_EVENT, handler=handleNotification)
I am using a Wipy to collect data from my BLE sensor. I decided to use the characteristic notification instead of reading the sensor data periodically as the sensing time interval is not regular.
I just extract the essential code as the above.
I am sure the Wipy was connected to my BLE sensor as I was able to read the data manually. However, the Wipy never receive any notification while the BLE sensor was pushing out the data.
Is there any thing I missed for notification configuration? Thank you so much
