Android & BlueNRG2 [Copy link]

 

I wrote an Android app and used the following Android code to send a character. I want to know which callback of Bluenrg will be called after sending the character?

BluetoothGattService gattService =

bluetooth_gatt .getService(java.util.UUID. fromString (serviceUuid));

BluetoothGattCharacteristic gattChar = gattService

.getCharacteristic(java.util.UUID. fromString (characteristicUuid));

gattChar.setValue(value);

bluetooth_gatt .writeCharacteristic(gattChar);

There is no error when running android studio, which means the sending is successful.

Ansersion

bluetooth_gatt .writeCharacteristic returns true to indicate successful transmission.

I have made cc2541/cc2640 APP, but never BlueNRG. Hope this can help you.

You can look at this example and find the code to receive data via Bluetooth and print it to the serial port.

The sent byte is received in aci_gatt_attribute_modified_event.
