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...
PAN #9 in the nRF51822-PAN-v2.4 document provides a workaround for non-functional OUTINIT. This question and this one improve the workaround and state it's unnecessary in...
We have used the first version of the S132 softdevice with the Engineering A version of the nrf52 chip. Now with the newer Engineering B version, we have moved to the second...
Hello Everyone,
i am trying to simulate the circuit using Proteus so can anyone tell me where can i find the Pspice model files for the Nrf51EVB is it available? any suggestions...
Hello to everyone.
I write code for NRF24LE1 using KEIL and rtx tiny. But i have some problems.
When i power on my device, programm don't run correctly, but when hard...
Hi experts,
The softdevice is s120. I get error code BLE_ERROR_NO_TX_BUFFERS after calling sd_ble_gattc_write() several times. I want to ask what does the tx buffer mean...
I have a strange problem on my target nRF51822. When I try and use the UART interface between my nRF51 and my host MCU, it causes the nRF51 to reset and the RTT terminal to...
Hi,
I've been playing with NFC on nRF52. It sends "Security Manager TK Value" over NFC. There is currently no option to use LE SC over NFC in examples, which is to send...
Hello
I have an problem using I2C on my custom board which uses an Nrf51422 SOC.
I have an RTC chip connected to it and I have no idea how to use your libraries.
The...
Hi! I'm using Arduino BLE micro and good results so far. With some accellerometers connected via I2C.
Today I have a strage behaviour.
I connect the arduino, ok, open...
Hello everyone,
I have a nRF51822 dev board connected through USB to my PC.
I have connected it to COM5 using Terminal and now I would like to interrogate BLE like we...
Hi guys
I have a custom board with NRF51422QFAA, load "s310_nrf51422_2.0.1_softdevice", program on "nRF51_SDK_7.2.0"
the bootloader I used is "dual_bank_ble_s310"

Is there a way to control the max # of packets be transmitted in one connection interval?
(We want to vary it from 1 - 6, knowing that nordic can support up to 6-7.)
Has anyone had any success setting the configuration register on TMP102/112 temperature sensors via I2C? I'd like to switch the sensor to one-shot mode to further minimise...
Hi everyone !
I'm trying to send data from an nrf51822 to an nrf24l01 with arduino and I guess I'm doing something wrong...
For the moment I succeeded to have these talking...
