WICED Studio Wi-Fi Combo

joMa_1809706

SDK 4.1.1 with Cypress CySmart 1.2 connected to a pc via a cypress dongle.

I started with the unmodified demo program (demo.ble_wifi_introducer-BCM94343W_AVN download run).

I fixed the platform.c file with the suggested fix.

The suggested fix in wiced_bt_cfg_settings is already there.

I have tried increasing WICED_BT_CFG_NUM_BUF_POOLS.

I see lots of comments that this problem still exists in sdk 5.

Should I just give up on getting the demo to work and go elsewhere for a BLE/Wifi combo solution?

Hi John,

Could you test on Wiced 6.0? I tested the example on Wiced 6.0 on a 94343WWCD1 board and I didn't get the error.

Hi yssu

Take a look at mycase 366598.

I'm sure it still has chance to hit GKI_exception!!

And take a look at the changelog, you will find it does not mention any

fixes regarding GKI_exception/getbuf: out of buffers.
