How to use NRF51822 for IOT communication via UART

[karan]

Hello Everyone,

I have created an schematic for m custom prototype using NRF51BLE with Sigfox Radio chip whenever i press the button on the NRF51i has to send message to sigfox and the Sigfox radio transceiver used to communicate with NRF51 via UART so could anyone help me how to interface sigfox radio via BLE NRF51

can anyone propose me some idea how to define the software to interface both SOC any idea or suggesion would be helpful thank you

In this respect, the nRF5x is no different to any other microcontroller - the "Sigfox Radio chip" neither knows nor cares what host is used.

So just study the documentation for the "Sigfox Radio chip" to see what it requires; look at the examples, application notes, etc, provided by the manufacturer.

Yes you were right based on the information i found on the manufacturer datasheet they have mentioned to use the SPI interface (SI,SO,swclk, cs)These are the four pins needed to be connected to the host MCU but in the other google search they mentioned you have to use to UART TX/RX)interface to cmmunicate our radio to the host MCU so i am little bit confused how o proceed further could you help some ideas

If you have issues with TI's documentation, then you need to be asking TI about that!
