Did you connect a debug terminal to your BLE device and confirm you did not crash it ?

Its iOS app using Nordic type app with custom framework. While a tried to update 3 character then only it crashed. I was able to update single character successfully... like date

written code:

let bytes : [UInt8] = [ 0x00, 0x09, 0x98 , 0x88, 0x83, 0x92, 0xD3, 0x39, 0x39, 0x39, 0x39, 0x39 ] let datar = Data(bytes:bytes) deviceNameCharacterToUpdate?.service.peripheral.writeValue(datar as Data, for: deviceNameCharacterToUpdate!, type: CBCharacteristicWriteType.withResponse)

    let bytess : [UInt8] = [ 0x43, 0x67, 0x61 , 0x6E, 0x64, 0x72, 0x61, 0x20 ]
    let dataLoca = Data(bytes:bytess)
    locationCharacterToUpdate?.service.peripheral.writeValue(dataLoca as Data, for: locationCharacterToUpdate!, type: CBCharacteristicWriteType.withResponse)

    
    let data = self.dataWithHexString(hex: hexDateToWrite)
    dateCharacterToUpdate?.service.peripheral.writeValue(data, for: dateCharacterToUpdate!, type: CBCharacteristicWriteType.withResponse)

Give more details

What BLE device are you using e.g. what firmware are you running in it, what App e.g. iOS or Android are you using.

etc

BTW. If its your own custom firmware in the BLE device, it sounds like you crashed it while writing those 3 characters
