characteristics

Can anyone help me with the AT command to write characteristic value, Or how to send data from arduino to another ble device using Hm10 module. The HM10 after sending the AT+START, does advertise packets, and can detect the service and characteristic, But the characteristic value is the default 0x00, How can I change that? Have checked the data sheet multiple times but can not find an AT command that is capable of doing the same. UPDATE: Similar problem with setting the HM10 in Central Mode: Central Mode Setup! 1) AT+ROLE1 - Set up to Central Mode 2) AT+IMME1 - Start from RESET 3) AT+SHOW1 -

How to read BluetoothGattCharacteristic properties like is characteristic Readable , Writable or Notifiable . AZ_ /** * @return Returns <b>true</b> if property is writable */ public static boolean isCharacteristicWritable(BluetoothGattCharacteristic pChar) { return (pChar.getProperties() & (BluetoothGattCharacteristic.PROPERTY_WRITE | BluetoothGattCharacteristic.PROPERTY_WRITE_NO_RESPONSE)) != 0; } /** * @return Returns <b>true</b> if property is Readable */ public static boolean isCharacteristicReadable(BluetoothGattCharacteristic pChar) { return ((pChar.getProperties() &

I am developing BLE in Android , I can scan, connected and write characteristic to to the BLE device. I call the following function to pass BluetoothGatt and characteristic to AsyncTask when click the Button . write_btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { new WriteCharacteristic(mBluetoothGatt , HueCharacteristic).execute(); } }); The code of write characteristic is like the following: private class WriteCharacteristic extends AsyncTask<String, Void, String> { public BluetoothGatt mGatt; public BluetoothGattCharacteristic mCharacteristic;

I've got a Polar h7 device around me right now (it's BTLE) and I've got everything working but I am confused about how to get the BPM our of the characteristic.value now that it is updating. I have to turn some bytes into bpm... My peripheral is updating: func peripheral(peripheral: CBPeripheral!, didUpdateValueForCharacteristic characteristic: CBCharacteristic!, error: NSError!) { if characteristic.UUID == CBUUID.UUIDWithString(heartRateChar) { getInfoAboutHeartRate(characteristic) } } I am getting info about the heart rate: func getInfoAboutHeartRate(characteristic:CBCharacteristic) {
