how to transfer data from nRF52840DK to raspberry pi 4 without deploying bluetooth ble5 ?

[NRF52840DK&dev]

hello

i want to send the data from my 5 of nRF52840DK to 1 of raspberry pi4  , i known the nRF52840dk has built-in bluetooth ble5 and raspberry pi 4 also integrate bluetooth ble5 as well

BUT i do not want to send data with the bluetooth channel ,**  i want to transfer or send data from 5 nRF52840dk to 1 raspberry pi 4  WITH CABLE ** via GPIO pin or UART or SPI , i do not  know much about those , 

 how to send data from 5 nrf52840dk to 1 raspberry pi 4 with cable connection ?

Hi

1. I would go ahead with SPI if I were you, but would keep this in mind, and make sure to do thorough testing to make sure it works as intended.

2. Yes.

Let me know if we can close this case now, or if you have (or might have) follow up questions we can leave it open for now.

Best regards,

in this moment , we can close it , because i can not find the new raspberry pi 4 that being available to ship me ,  all are sold out ,so i could not test SPI communication between both devices  i have only nRF52840DK in my hand , and i do not want to buy used or refurbish raspberry pi4 , i want to buy new one , and adafruit raspberry pi 4 distributor will be ready to ship it again ,problably the end of March , once i got raspberry pi 4 ,maybe the end of March ,and start having problem of sending data with SPI between 1 raspberry pi4 and 5 nRF52840DK  or i could not configure coding of 5 SPI instance communication , i will ask again by open new ticket
