I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...

HI team.
I use experimental_ble_app_buttonless_dfu example to do test. But it doesn't work after...
Hello All,
I'm trying to get my application based on a nRF52832 to use as less power as possible and I've noticed that when the nRF_LOG UART is enabled it draws around...
About DM_LOG, DM_ERR, I define ENABLE_DEBUG_LOG_SUPPORT in Options for Target->C/C++->Define, the "string" will be sent over UART.
But ADV_LOG still does not work，How should...
Hi Nordic,
I am using ESB_DPL SDK ver 13 for communication between one nRF51822 transmitter and multiple nRF51822 receivers with data whitening. I do not want the receiver...
I ported both the provisioner and provisionee program respectively to 2 different boards, but couldn't detect the advertising package of neither.
Do they send exclusively...
Hi all
I've two questions regarding errata 156:
Am I assuming right that, as long as I don't use WFI or WFE, this errata has not effect?
Are the two consecutive...
Hi. I'm using nRF52832.
I want to add LEDs. Can it drive 20mA for LED?
As I see the datasheet, GPIO pins have "High drive" function. What deos it mean?
I hope your reply...
Hello,
I am having difficulty downloading an application using the sample images provided. It looks like the application boots into the bootloader, there is a brief message...
Hi,
I modified the blinky_freertos example from SDK 12 slightly to perform the following:
I have one timer and one task. The task blinks a LED and then suspends. In...

Hi There,
I am doing current measurements on the nrf52840 in sleep mode with no RAM retention and I am getting different values based on how I take the measurements. Please...
I am attempting to interface a Winbond flash device with the NRF52. The
datasheet does not specify the idle state of MOSI when reading from the device. However, I cannot...
We started with the default project that have no heap.
Added mallocs to the system and they seemed to succeed, without realizing heap was set to 0. They did not return NULL...
