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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hello,
I was wondering if anyone has had success communicating with the nRF24L01+ eval kit and a Raspberry Pi. I have found several examples through Google and am trying...
I am requesting the softdevice to start/keep the 16Mhz crystal oscilator running with the following code:
// Request 16 MHz crystal oscillator
err_code = sd_clock_hfclk_request...
Hi,
I have Nordic Nrf51822 custom board.
in that we have spi Nor flash.
i check the spi read and write with an application without soft device enabled.
which is...
Hi all,
I'm having problems when linking my code intended for use on the nRF51822. For some reason there are missing symbols that are needed. I've traced the dependencies...
Hello,
Does Keil's Lite/Evaluation MDK-ARM tool chain version suffice for development work on nRF51 devices? Please advise!
I have seen questions about using GCC and...
I'm using the s110_nrf51822_5.2.1_softdevice with the NRF51822. If I understand correctly, after pairing the NRF51822 with a phone, a long term key has been generated and...
Hello,
I decided that bonding (does it equivalent to "pairing"?) is not allowed in my application, so I modified the following definition in main.c:
#define SEC_PARAM_BOND...
We are trying to get the ANT feature to run based on RTC as follows:
a. Timer RTC0 or 1 (1 for this example - tick is disabled, compare is on.)
b. Timer initialized (all...
Hi,
I'm a new learner for the nrf51822. In the SDk ,there is an example of esb which is used for the radio transmittion with ACK. I want to know that if I can use the esb...
We have a custom board designed based on N51822, CEAAB0 and we have used the chip antenna from ST BAL-NRF01D3. When we have flashed our proximity code to the device, we will...
Hi,
After i use sd_ble_gatts_hvx() ,i will receive a BLE_EVT_TX_COMPLETE.
The "tx_complete.count" is no problem when i use softdevice 5.2.1 . e.g. count =1. this is correct...
Dear Sir,
i am using pca10001.
Actually i tried to read and write the data from EEPROM having address 0x50 though i2cbus.
i made po.0 and p0.1 as output pin then...
Hi,
I've created a small test program (pasted below) that is intended to help me profile some of my code down to us resolution. Maybe you can quickly run it (no other files...
I'm designing a board using the nRF51822 and leaving test points on the PCB for the programming/debug lines so the chip can be programmed after PCB fab. Are there any reference...
