For debugging, I am trying to answer the question whether the UART communications between the BT module and the STM32F4 processor is using RTS/CTS flow control.
I am using the WICED BT stack on the Avnet BCM4343W IoT Starter kit BT module, and I would like to observe the RTS/CTS behavior on a logic analyzer. I do not see these signals available on the AES-BCM4343W-M1-G card edge connectors, nor the Avnet board's shield connectors.
I do not have access to the internal schematic of the AES-BCM4343W-M1-G module. Are the RTS/CTS/RXD/TXD signals between the STM32F4 processor and the BT module accessible anywhere on the board? I just want to verify that the WICED stack behaves the same way on the Avnet board as the Nucleo board.
