Hi all
I'm using the GATT server on the nRF51822 with the SoftDevice S130 V2.0.1. I've implemented a service and a characteristic which supports only write requests (including...
Here is my question.
I always disable uart after I send data.
NRF_UART0->TASKS_STOPTX = 1;
NRF_UART0->ENABLE = UART_ENABLE_ENABLE_Disabled;
this was write in the...
Is there a compiler/makefile flag that allows for 64bit printing?
I have included inttypes.h, and tried both %llu and "PRI64" as shown:
char scrbuf[30];

Hi
We are using NRF52 and SDK 11 and S132.
The nrf52 acts as a central and selectively connects to the closest phones (ios) that are acting as a pheripheral.
For this...
hello,
nordic's engineers, need your help.
(1) the first problem : can not set VDD output to 3.3V
From nRF52840_Product_Specification_v0.5, it says:
