open PUART with Modus SDK

[wenchilo]

Hi,

I am developing on CYBT-343026 with SPP on Modus. And there are two problems

1 . I can search and but can't connect to the eval board from my SPP藍芽串口 on Redmi K40

2 . I can receive log from HCI Uart but I can't receive anything from puart.

I just run the deafult sample code without any modification. What could be the problem.

By the way, my Modus is version 2.4

Hi,

Is this connection problem only when you use Redmi K40? Have you tried using any other peer device?

Please uncomment wiced_set_debug_uart( WICED_ROUTE_DEBUG_TO_PUART ); to route the logs to PUART.

Thanks,

I uncomment wiced_set_debug_uart( WICED_ROUTE_DEBUG_TO_PUART ), wiced_hal_puart_select_uart_pads( WICED_PUART_RXD, WICED_PUART_TXD, 0, 0) and comment wiced_set_debug_uart(WICED_ROUTE_DEBUG_TO_WICED_UART). Now the puart works, But the bt connection still failed. I have tried two different app on two different phones. And both of they can't connect to my eval board

I think this might be the problem

Hi,

I could see similar disconnection issue when I tested the spp app on CYW920706WCDEVAL. I see some L2CAP disconnection. Our FW team will be fixing this issue in the upcoming SDK - BTSDK3.3.

If possible could you please share the logs collected at your side using btspy to confirm the issue? 

Thanks,
