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...
Besides the fact it's a later release?
i.e., why does one have "nRF51822" in the name and the other simply "nRF51" ? Is it because the former will only work on a 51822...
Hello,
I have the Bluetooth Smart Beacon Kit along with the Dev kit (J-Link Lite and other eval boards). I am using the nrf51 SDK version 6.1.0.0 in eclipse along with GNU...
I have a a new pca10028 DK board and a pca10000 dongle. Using Keil v5.14 and Nordic SDK v7.2 I can compile, download and test several pack examples (e.g. ble_app_hrs, ble_app_alert_notification...
We need to develop a system that can receive multi heartrate ANT+ strap signal at least 50 to 100m range. Im newbie in this technology and I don't know if is there any antenna...

HI,
I add a readable and writeable characteristic with :
attr_md.vloc = BLE_GATTS_VLOC_USER;
attr_md.vlen = 1;
attr_md.wr_auth = 1;
and
attr_char_value.p_attr_md...
Hi Guys,
I'm doing a test between CC2541 and Nordic NRF51822. The CC2541 work as a peripheral role. NRF51822 as central role. But CC2541 can update another CC2541 that...
I'm working on a design that requires an adc reading to be taken on a pin that is also used as an interrupt. I've looked at the reference manual but am still confused as to...
The end of memory bss is @ 0x20002DAC (11692B).
The start of the heap is @ 0x20002DB0 with a size of 2560B.
The heap ends at 0x200037B0.
The stack works back from the end...
Hi,
I intend to buy the NRF51822 beacon to use it to transmit data from an SPI-linked sensor. Is this feasible? (It seems so, but I just want to make sure). Also, will I...
Yesterday was the nrf Beacon application for Andriod Studio released. I added the project DFU library to the same folder as described. But I get an error:
