connecting sim800l and neo_6m to nrf52840dk

[rania amara]

hi , i'm  trying to connet sim800l and neo_6m  modules to nrf52840dk using zephyr ,however i can't find any code source to use .,or do i have to creat the code from scratch if so can you give me the main steps to do

Hi Rania,

You can learn how the use two uart ports on nrf52840dk, because both sim800l and neo_6m use uart port for communication. 

After you can communicate with two modules, you can develop your application logic.

Best regards,

Charlie

hi , i'm having trouble in using uarts ,since i'm using 2 modules do i have 2 use uart0 and uart1 or i can use just one uart

There is a sample you can get to start Low Power UART — nRF Connect SDK 2.6.1 documentation (nordicsemi.com). You may use one uart to switch between these two modules, but this will make your hardware and software design complex and may introduce some limitation since two modules can not communicate with host at the same time.

Best regards,

Charlie
