Hi, is there an available developer in my tri-state area of Minnesota, N. Dakota, or S. Dakota? Please call me if you are available for a project for hire. The developer should...
I'm trying to design a very low power sensor that takes readings using ADC and SPI 200 times a second. I'm a bit worried by the current EasyDMA uses (1.1mA). As far as I can...
Hi, I am working on a project where I want to make one nrf51288 chip as central hub and connect that to a android phone and other salve nrf51288 .

Hi,
I have a code programming the nRF51422 development board to write to a Sharp Memory 96x96 pixel LCD screen using SPI.
Currently the code writes two numbers and a...
I've modified the ble_app_uart example by adding GPIOTE so that the transmitter sends a character to the receiver when a GPIO pin is toggled. This part is working well.

Hi,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
That is probably an old topic, but after doing some research I could figure it out: calling sd_app_evt_wait() on my nRF5832 + nRF5 v11.0.0 SDK + s132 causes my chip to reset...
Hi
I've some troubles with the ble disconnection of S110.
Always when I call the sd_ble_gap_disconnect function after successful connected, the error code 8 NRF_ERROR_INVALID_STATE...
As I can see, I flashed Zephyr to Carbon 96 board, I don't fully understand the process,
I mean, I see .bin and .elf files but i don't see boot.img file, how do i make a...
The nRF52832 datasheet refers to a transmission of multiple packets in Figure 37. I have attempted to load multiple packets to the radio FIFO using nrf_esb_write_payload(...
Hi All,
I have developed an application on the RedBear BLE Nano2, and am trying to port it accross to a custom nRF52 board.
The Hex that the Arduino IDE outputs does...
I have an application which requires protection from passive eavesdropping, but not man in the middle attacks. I want to enforce the use of diffie hellman key exchange.

Hello
i am using Nrf52840 with sdk 132 and version 12.2
i am using the Heart Rate example as template.now i am just testing.
Before making connection,i like to Advertise...
I have a sensor which has output in the range of 0-5V. I want to connect it to an nrf51822 GPIO pin and to be able to read the value via it's 10 bit ADC. Is there any guide...
hello, there my application is like that...
(1) calculate size of receive buffer. than read that size of data.
again new data comes, then again calculate that size of...
Issue: With my external antenna design, I get lower dbm than PCB antenna (nRF51DK) with same distance.
My external antenna design: -70dbm
nRF51DK: -40dbm
In this...
Today when I started power profiler kit, it suddenly started to show peak values like 80 mA. This has not happened before, but the values with the same hardware have been...
In the data sheet of the NRF51 and 52 there is mention that sensitivity of NRF51 is -96 dBm and NRF52 -98.
But I read some where that when RSSI is -90 then that signal...
We are working on a dynamic radio power change for a proprietary RF protocol, and we are missing some granularity on the NRF_RADIO->POWER levels.
Typically we would need...
I am wondering what is the logic and magic behind using sdk API's to advertise vendor specific 128-bit service UUIDs. In the "Nordic UART Service" example (nus, SDK12.2.0...
