Ble transmit not working on IOS

I want to send data to HM-10. App on Android works fine, but on IOS - not.
On IOS - app connects to HM-10, but when i push “SEND”, there comes errror:
“characteristic 0000FFE1-0000-1000-8000-00805F9B34FB write failed for device my device ID and service 0000FFE0-0000-1000-8000-00805F9B34FB”

i have seen the same problem in topic here, but dont see response I've got a problem with BLE component and the JDY-10-v2.4 module

Hope i can get help here…
