TDA2SX: hciattach fail with the EMMY-W161 Module for Bluetooth

Zinal Prajapati

Part Number: TDA2SX

Hii -all,

We have an TDA2sx board with EMMY-W161 module onboard, running Linux kernel 4.14 with BlueZ stack enabled.

We modified the UART port assignments for interfacing with the EMMY-W161 HCI UART lines, and tried various pinmux options enabling/disabling RTS/CTS.

When we use the TI-specific profile with 'hciattach', it switches HCI comm-link to faster baud rate with flow control enabled, but getting error like Unknown HCI packet type 00.

Here is the log,

root@dra7xx-evm:/opt/vision_sdk# hciattach /dev/ttyO6 any 3000000 flow

Hi,

Have you checked with EMMY-W161 module vendor for correct settings to use?
Also, what do you mean by "TI specific profile"?

Hi Zinal,

Before it was working on the same board?
Make sure the baud rate you are using is compliant with this module.

Hello Sir,

Yes Sir I checked with same board and with other board also. And with this Same Buadrate 3Mbps i have checked. And i cross verified my all configuration again nothing has changed it's same like before it was.

Hi Zinal,

Few more questions, I am still not clear.

This was working before and now it's not working?
What changed now?
