External MCU with nRF51822

[tvu1020]

Hi,

I'm planning to use an external MCU to process my digital signals and send it through nRF51822. Do I need to develop an on-board antenna? TI has the module CC2541 from ChipCon where I don't need an antenna and can just send through via UART.

Please advise on any other solution with Nordic components!

Thanks, Trung

Hi, for this pourpose we prepared a special solution - serialization. Most of the examples in our SDK have also serialized versions for different PHY layers: UART, UART HCI, 6-wire SPI, 5-wire SPI (those are interfaces between an external MCU and nRF chip).
