1160+1ZM and BT SPP profile

[kostya740]

Hello, I need your help.

I have MIMXRT1160-EVK witn 1ZM M2 WIFI-BT module.

I was import edgefast_bluetooth/spp example from 2.13 SDK.
Modified define to WIFI_88W8987_BOARD_MURATA_1ZM_M2 in a app_config.h

Build finished it without any errors.

Flashed without any errors.
But it is not working. In a terminal, I see only part of output "[sdio] E"
At pin SDIO_CLK I see 400kHz frequency, about 200ms from board start only.

Help me please with this example.

Hi @kostya740,

I'm sorry for the late reply.

Could you please tell me if you have removed R183 and added 0ohm resistor at R404 on your board?

Regards,

Daniel.

Hi @kostya740,

Could you please help me with the following information?

• Are you using external power?
• Are you able to run a Wi-Fi example?
• Did you do the hardware rework as stated in the Hardware Rework Guide for EdgeFast Bluetooth Protocol Abstraction Layer?

Regards,

Daniel.

Hi@DanielRuvalcaba 

Thank you for help.

1. Yes. External.
2. I tried. Didn't work too.
3. No. I will do all the need. Thanks.

Do you have another idea? Why didn't BT/WIFI examples work?
