I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
Hello,
I am working on an application where the nRF51 acts as both central and peripheral. The device is in permanent connection as peripheral while scanning for other devices...
Hi
can ESB be considered RealTime transfer as soon as it has it's timeslot?
Outline of use-case:
Device advertises existenace on BLE
If there is data waiting...
I am trying to implement a REQ line protocol over GPIO to signal to the Master when it is ok to receive data. Basically, I want to pull the REQ line high when the nrf51 has...
Hello,
Ble spec says that "new alert" characteristic - field: "category ID" can have 1 or 2 bytes.

But it seems in your struct you let it have only 1B.
typedef...
Hi,
I have ordered a PCB using the reference schematic for NRF51422 user guide.
I wanted to know whether the schematic has the required antenna design or I need to add...
Hi All,
I have a basic question about advertsing data, more precisely about device's address.
I try to disable in my advertising data, the address field but it doesn't...
Hi I followed the Nordic UART example code to read and write characteristics to a Nordic S110 nRf51822 device.
My code is the same as in writeRxcharacteristic but when...
When I'm single stepping my nRF52 application in Keil with a BLE connection I always get the softdevice_fault_handler called.
I'm using SD 132, v2.0.0 and the the parameters...
What is the maximum clk frequency that can be output on a gpio for the nRF52832 ? I want the nRF52832 to output a clk signal on any of the gpios to an external module, and...
Can anyone please suggest a simple example on initializing SAADC Driver on one pin and do a simple blocking ADC read?
Sorry for a very broad question - but rather to ask...
I'm using the nRF52 Dev board and set the --rbp ALL option while using nrfjprog. It worked fine, and I am able to do OTA updates as I was testing the bootloader example. But...
Hi
I'm doing one project that is taking data from uart and send to mobile app. I'm facing one issue that is when I connected to peripheral it connected and take data from...
I'm looking for some options to extend the PCA10028 with a keybord and a numpad. This would give great options to play around with passkey topics.
As the PCA10028 supports...
Currently we are considering whether we should use external Flash Memory or NRF52 Internal Flash.
External Flash memory has a lot of drawback in comparsion with internal...
Hello,
I am trying the ANT-OTA DFU Update using an ANT Stick and the nr51422 pca 10028 board. The ANT Updater shows that the Image Upload is completed. I am uploading the...
