From 13d812a7188f0b0ecaa07ee66e376a2c5a88742f Mon Sep 17 00:00:00 2001 From: Dean Camera <dean@fourwalledcubicle.com> Date: Thu, 3 Jun 2010 08:42:20 +0000 Subject: [PATCH] Delay needed in bluetooth code due to the send function not waiting for the pipe bank to become ready before writing. Add in a call to Pipe_WaitUntilReady() to fix the issue. --- .../Incomplete/BluetoothHost/Lib/BluetoothACLPackets.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) diff --git a/Demos/Host/Incomplete/BluetoothHost/Lib/BluetoothACLPackets.c b/Demos/Host/Incomplete/BluetoothHost/Lib/BluetoothACLPackets.c index 818caac75..698210488 100644 --- a/Demos/Host/Incomplete/BluetoothHost/Lib/BluetoothACLPackets.c +++ b/Demos/Host/Incomplete/BluetoothHost/Lib/BluetoothACLPackets.c @@ -32,7 +32,6 @@ TODO: Make SendPacket respect receiver's MTU TODO: Make ReceivePacket stitch together MTU fragments (?)
