RT1170 EVKB bluetooth example not working

[jeffrey_su]

Hi 

I got a RT1170 EVKB, with a ublox AW611 combo module, the wifi works fine.

But I tried several Edgefast bluetooth samples, just can't get the bluetooth works.

I add WIFI_AW611_BOARD_UBX_JODY_W5_M2 define, 

also tried CONFIG_BT_IND_DNLD, 

but it seems the uart is not working, it can not read correct status from uart.

Is there any other configurations I missed ? Or even hardware rework need to do ?

Best Regards!

Hello @jeffrey_su 

You need to rework board to enable uart via M.2. See attached link:

Rework Guide for EdgeFast Bluetooth Protocol Abstraction Layer — MCUXpresso SDK Documentation

Hi @shaun_wu  

thanks for your reply,

I saw that page, too.

but which one should I follow ? 

most of these documents are tagged with murata. But my module is ublox.

Or should I just follow Hardware Rework Guide for MIMXRT1170-EVKB and Murata M.2 Module to rework my board ?

Could you please tell me exact which document I should check ?

Hello @jeffrey_su 

You could follow Murata rework, RT1170EVKB side rework is same.

Hi Shaun

Thank you very much

We try to rework accroding to the document, 

although the example doesn't support module ublox iw611 M2, it pass thought bt init, uart communication seems work fine.

But I tired several display example which works fine before the rework, and encounter hard fault(HFSR), so I'm wondering is this because we did something wrong with the rework? or it's because display and M.2. uart functions are mutually exclusive ?

Best Regards and have a nice day
