[irda-users] No Link activity while receiving files on IrDA
|
From: Alim A. <ali...@gm...> - 2008-04-17 05:22:08

Hi Group/Samuel,
I am facing a very strange problem with my IrDA setup, My board is imx21
based custom board, and kernel version is 2.6.18.
As far as device discovery is concerns, my board is able to discovery my
sony ericss phone successfully, but when I am trying to transfer a file from
the phone_to_Borad (irxfer is running on board), its give me a warning like
IrLAP! no activity on link! and through some dump and connection lost and
device discovery will fail, but if I reboot the board and try the same steps
after sometime, device discovery is working again. Please have a look on the
'irdadump' log below, and give me some idea what could be the possible
reason for the same.
many thanks in advance.
