nRF52840 as network co-processor

[Ramsay]

I want to connect esp32 with nrf52840 for availing Bluetooth 5 functionality. In this, I want to use esp32 as application processor and nrf52840  as network co-processor. Is there any examples which I can try to implement this functionality ?

A connection diagram if possible will be helpful for clear understanding.

Hey Ramsay,

Read the Serialization library documentation. 

Cheers,

Håkon.

I'm new to nrf Ecosystem and I tried this code on esp32

https://github.com/espressif/esp-idf/blob/master/examples/peripherals/uart_async_rxtxtasks/main/uart_async_rxtxtasks_main.c 

and I'm unable to read the data on nrf52840

I'm not familiar with ESP32.

I suggest you use the virtual serial port of the DK's on-board debugger. Connect the DK to a computer via USB and open a UART terminal on it's associated COM port. Then you can test the serialization FWs UART interface without using an external MCU (as a starting point).
