nRF52832 3-wire HCI UART (H:5)
Hello,
We have some hardware which has a linux host and an nRF52832 Bluetooth IC. Unfortunately only RX, TX and GND
is connected but no hardware flow control lines. We are therefore required to use the 3-wire UART HCI protocol, also
known as H:5. Zephyr does not yet support this, I was hoping that NimBLE does.
I have compiled NimBLE and set flow control off my overriding the following cofiguration variable:
BLE_HCI_UART_FLOW_CTRL: 'HAL_UART_FLOW_CTL_NONE'
I'm not convinced that this is enough to switch to the 3-wire UART protocol. Could anyone give me some pointers?
Kind regards,
Daan Pape
