CC2564MODA: wake-up issue

HRi

Part Number: CC2564MODA

Hello,

We have initialization issue with the CC2564MODA, We are using 3wire UART communication and we see that we are sending messages over the UART but we are not getting any response from the CC2564MODA,

We have checked the CC2564MODA power pins including the NSHUTD and the SLOW_CLK_IN and they are looking good, We can't check the HCI_RTS to see that it is going low as we don't have access to it, any other way to check if the CC2564MODA is up, what is the TX_DBG pin used for?

Many Thanks,

HRi,

The TX_DBG pin is used to collect the BT firmware logs from the CC256x Bluetooth controller.

You can capture the firmware logs from this pin to get a better idea of whether the controller is being initialized properly.

The 3Wire UART, according to the BT core specification, is the H5 protocol and uses the Slip layer (details in the BT core specification document). Are you using the H5 protocol?

Best regards,
Vihang
