Hi,
I want to send data from one peripheral(nRF51 DK) to multiple Android Phones. This will be a one way connection from the peripheral to the smartphones. I red on the...
I am working on "nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_central_and_peripheral\experimental
\app_s130_demo\pca10028\s130\arm4" project .
In this project,in which variable...
Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...

Hi!
My BLE peripheral needs to change its "static" passkey under certain circumstance.
However, when I attempt to connect after setting it, I get a PM_CONN_SEC_ERROR_PIN_OR_KEY_MISSING...
Hello everyone,
I'm trying to interface a NiceRF LN610 LoRaWAN chip to nRF52840 via UART. Initially, I tried communicating with the chip using CP2102 USB-to-TTL module and...
Hi,
In order to measure the RF power, I measured the RF power by radiating inside the RF shield box.
But there is something strange.
The position between the device...
Hi ,
I want to develop the firmware to read the nfc tag and read the sensor data send to the application via BLE I have read many post regarding nfc . Let me explain what...
Hi,
I am working on temp. sensor with nrf52832 dev kit for firmware testing and development and also using nrf52810 for product testing.
in my code, I merged twi communication...
hi,
I want to develop a project based on ble beacon mode and ble app hts code.
and I am using nrf52810. so will it work if I merge both codes and use for this project...
I know that nrf_cal_set_time() from the nrf calendar example is NOT meant to be called on a regular basis / should only be called to update the time being kept locally to...
Hi,
We are looking for a guideline to trigger GPIO and SAADC sampling at the same time.
Our purpose is to sample every 20 m
Hi,
We are looking for a guideline...
Hi, We have a DFU OTA process that was functional, but updating our softdevice to s113 7.2.0 has left us with a problem - since the softdevice does not exist in the nrfutil...
Hello.
I am doing a small project where nrf52 reads data from a BME280 temperature sensor via SPI and sends it using ESB.
I have no experience with radio, so I use a ready...
I would like to use the NRF24L01+ from a 3v coin cell, but interface it over SPI with a 1.8v-powered microcontroller. Assuming the uC is tolerant of the NRF SPI outputs, I...
We have a application where data transfers happen through a mechanism where the external client does a write-without-response to send in a command. The response to the command...
I am busy with my first BLE project , programming a custom service for both pheripheral and central role. I have already finished the pheripheral service, using a custom service...
There are other GPS modules on the market which can give information like "the device is within 10 meters of the given coordinates". Is there a way to either get this information...
Hello,
i am using AES CCM encryption available in nrf52832,
my data which need to be encrypt is same every time. data will encrypt and 4 byte will add at the end of...
