media button become invalid when ble mouse reboot and connected to PC

[gootoomoon]

When I connect my ble mouse to the PC win8.1 , media button works normal.

When I power off and power on my mouse, it reconnected to win8.1 PC quickly, sensor ,left button,right button works well but media button.

I must remove ble mouse from win8.1 and research my mouse and connect it media button work again.

Why this happen? How can I make media button always wokes well when mouse connected to the win8.1PC?

Hi,

Is it the same behavior if you use master control panel as well? Do you power the mouse on/off very quickly? Is it the same behavior if you wait 10 seconds before you power on the mouse?

Sometimes it works well when I reboot mouse after 10 seconds but sometimes not.

And it will send some media button auto.

I will add some print and check it again.

I try to wait 20s and power on my mouse behavior still there.

My dongle used for ble-sniffer how can I turn it back to use as master control panel?

It seems that , when I connect to the PC and disconnected my ble device from PC then media button will be ok when connect again to the PC even reboot my ble device.

So it must be white list problem, because when ble device get the event of disconnected it will store something by "ble_bondmngr_bonded_centrals_store();"

And I try this:

1. when I erase all chip and program my ble app to the nrf51822 , connect to PC and mediabutton works well and

ble_hids_inp_rep_send(&m_hids,
                                         INPUT_REP_MPLAYER_INDEX,
                                         INPUT_REP_MEDIA_PLAYER_LEN,
                                         (uint8_t *)&mm_key);

will return 0

2. if I reboot my ble device and it will connect to PC auto , but ble_hids_inp_rep_send(); will return error code :"8". it means "Invalid state". And in this case left button right button works well but media button not.

I want to know that , is there any info from white list will be need for media button? Why other button and mouse move works well?

Hi,

If you open MasterControlPanel, select the dongle COM-port, then go to "file -> Flash programming", then you should be pointed directly to the master control panel .hex file.

Try this to see if the behavior is similar.
