Hello Dear BlueGiga Team/Users,

We used WT32i model in our development project with WT32i development kit. Now we need to send final PCB design to factory. 

When we bought WT32i development kit, there was iWrap firmware with module. 

So if we buy only  WT32i module(attached picture), does it come with iWrap firmware? Or do we need to program it after buying?

If it needs to be programmed, what is needed, UART or USB or SPI(there is SPI port, but did not use it. i upadted iWrap with UART port).

Thank you in advance.

Hello Friends,

Maybe it is bothering but I cannot find any way to get answer for my question.

I have posted question before related to mic of WT32i BlueGiga Devkit, but could not get answer.

Is there any way or method to check data which is received from mic of kit. I mean I want to use mic of kit by SCO OPEN command and getting different results.  But I cannot check if it is working properly or not?

Thank you

Mister@jrowberg, Thank you for your help.

I am facing some difficulties (maybe lack of my knowledge about DKWT32i).

I attempted several times to open audio connection, and there were several results

( NO CARRIER 0 ERROR 10d HCI_ERROR_REJ_BY_REMOTE_NO_RES, 

  HSP 4 OK and others). Maybe I am doing something wrong.

I need your help. Scenario as follows:

1. There is DKWT32i board and it is connected smartphone (OS Android)

2. We want to sent audio data from board to smartphone using mic of board when there is no any phone call.

It would be great if you could give some detailed example settings or approach. And also any way to check if data is received or not by phone.   Thank you!!!

Working with WT32i is getting more interesting and fun, so here comes another one.

There is mic connected to internal codec of Bluetooth, and it can be used in HFP, AVRCP and other profiles while receiving call. (here we can say WT32i is connected to phone). You speak to mic and voice data goes through BT and received by phone.

Is it possible to send voice data from WT32i devkit to phone in normal data mode using any profile(HFP/HSP, AVRCP...) when there is no any phone call? If it is YES, could anyone give hint or instructions, please.

Thank you!

Thank you so much.

Hello Friends,

I having problems with receiving calls on WT32i BlueGiga DevKit. 

I have set A2DP and HFP modes on board, and routed audio to I2S(External Codec). With playing music there is no any problem, but when I tried to receive calls I cannot pick up the call and voice cannot be heard via external codec. Voice is routing to internal codec's output, and voice is coming via internal codec's MIC.

Can I use external codec's MIC and HP OUT while receiving calls? If it can be,please let me know or any suggestions are welcomed. 

Thanks in advance
