(Putting this issue in the cordova-ble repo since it might be related to the underlying plugin code, and to keep BLE issues at one place.)

Developer reported calling writeServiceCharacteristicWithoutResponse() and getting error message:

LOG: Error: EASYBLE_ERROR_CHARACTERISTIC_NOT_FOUND 00001802-0000-1000-8000-00805f9b34fb:00002a06-0000-1000-8000-00805f9b34fb

This happened when using a Cypress BLE card: CY8CKIT-042-BLE Bluetooth Low Energy Pioneer Kit

Attaching file with test app that was used when this error occurred. There have also been reports of EASYBLE_ERROR_CHARACTERISTIC_NOT_FOUND when using the BBC microbit.
