Hello.
Recently I got CYBT-413034 Ev board for new project of my Company.
I have several issues.

[Env]
WICED
WICED-SDK Version: Wiced_006.004.000.0061
b38d42ee8368ff374b13514286120afd9e788a07
Update: Platform and New Patch Files For 20719B1 in WICED 6.4.0.61 - KBA228518
Target: SPP client (snip.bt.spp-CYBT_413034_EVAL download DEBUG=1 BT_DEVICE_ADDRESS=00167f1234a0)
I gave bd address using BT_DEVICE_ADDRESS option.
1. Board detect failure
-> I connect USB via PC with pressing "RECOVER"(SW2). it was only effective for me.
Currently I have to press SW2 button at every downloading. Is it correct procedures?
In addition, I also failed following recovery. It did not recover factory default.
Note: This will erase any user application in the memory and reset the board to the default state. Press and hold the RECOVER button (SW2).
- Press and hold the RESET button (SW1) for 1 second.
- Release SW1.
- Release SW2.
- Re-program CYBT-423028-EVAL.
2. Pairing failure
Following codes are in BTM_ENABLED_EVT.
--------------------------------------------------------------------------------------------
/* Allow peer to pair */
wiced_bt_set_pairable_mode(WICED_TRUE, 0);
// This application will always configure device connectable and discoverable
ret = wiced_bt_dev_set_discoverability(BTM_GENERAL_DISCOVERABLE,
wiced_bt_cfg_settings.br_edr_scan_cfg.inquiry_scan_interval,
wiced_bt_cfg_settings.br_edr_scan_cfg.inquiry_scan_window);
WICED_BT_TRACE("ret #1 %d\n", ret);
ret = wiced_bt_dev_set_connectability(BTM_CONNECTABLE,
wiced_bt_cfg_settings.br_edr_scan_cfg.page_scan_interval,
wiced_bt_cfg_settings.br_edr_scan_cfg.page_scan_window);
WICED_BT_TRACE("ret #2 %d\n", ret);
--------------------------------------------------------------------------------------------
-> From android, I search CYBT-413034 but failed.
What I did was...
1) Change settings
inquiry_scan_interval : 0x12
inquiry_scan_window : 0x12
2) remove write eir
// app_write_eir()
-> Android can search bd address only. If I give EIR information again, Android cannot search CYBT-413034 at all.
I found page time in snoop log(air sniff log) while android send "HCI_Remote_Name_Request".
In this situation, Android failed all pairing request. (Please see attached)
I also reviewed other samples in WICED and found there is nothing difference.
Of course I did this test with other android but was same.
It is basic bluetooth function so I am very confused.
Please let me have your advice.
