Subject: [PATCH 1/2] android/gatt: Fix sending incorrect frames
Date: Wed,  9 Jul 2014 10:53:52 +0200	[thread overview]
Message-ID: <1404896033-17337-1-git-send-email-marcin.kraglak@tieto.com> (raw)

Don't send pdu if encoding failed. It cause errors when trying
send notification larger than MTU - encoding pdu failed, and
length passed to g_attrib_send was 0. I caused errors.
