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'm using SDK 7.1, PCA10028 & PCA10003, SD310 2.0.1
My understanding is that the NFR51422 chip on the *28 board has twice the RAM, but otherwise is the same as the NRF51...
I'm using the nRF51 DK (pca10028) with the S130 0.9.0-1 ALPHA release and the experimental_ble_app_s130 example from Keil 5 doesn't work out of the box. Also I'm running 7...
This is Rajesh.C working for Sienna ECAD-Bangalore, India. We are using nRF51822 BLE in our design. I would like to know how many I2C and SPI device can be connected to the...
Hi,
I just receive a nrf51822 QFAC.
I'm using SDK 7.2 with Softdevice S110 7.1.0 with gcc.
If I compile using .ld from xxaa, It works (but using 16k RAM).
The same...
Hi, We have an nRF51244 and are using a single ADC in 10bit mode with a 1.8V supply (smooth regulated from battery) wired in LDO mode. The problem is our readings are all...
how many nrf 51 iot sdk devices can connect simultaneously to raspberry pi in your example setup...?
currently your device supports node role....when you will come up with...
Having just seen a couple of questions relating to DMA, which I was not aware existed on the nRF51822, I did a bit of digging, and it seems there must be newer silicon versions...
Hi all,
Please can anyone explain when the device_manager_event_handler() is triggred ?
And also, what difference between on_ble_evt() and on_sys_evt() and when they are...
Hi all,
I am using nrf51822, on pca10005 board, and debuging the s120/ble_app_hrs exple. I charged s120 v2.0 in memory.
The problem that I have is when ble_stack_init()...
Hi,
I apologize for the silly question, but I'm following this tutorial here:

Hello,
I have a Nordic nRF51822 board which needs to be interfaced with a MAG3110 freescale magneto meter sensor board. Need to measure X, Y, Z co-ordinates via I2C , please...
I have device from another company that has a n51822 chip for BLE UART communication and it can send data to my phone via an app with no problems. However, I am having difficulty...
When I add an attribute with BLE_GAP_CONN_SEC_MODE_SET_OPEN I get a BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST event when I try to read it.
I do not however get a BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST...
