I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...

I am toggling Value of slave through a button on nrf51822ek .This Value is displayed on MCP of dongle, but i have to get this value on terminal to send it to pi then through...
Hello, I am tryong to use to masters to communicate with two accelerometers.
Q1_ I found the following image from Nordic's website that shows SPI0 pins but there is no indication...
I can't seem to find the required current of NVMC doing erase and write. The product spec has only timings but not more. Could someone from Nordic provide some figures? Experimental...
Hi,
I have a C# app connecting to 51822 devices, doing data/firmware download. When I try to send erase page command (before write), erase works, but there is a disconnect;...
Should we keep track of this by monitoring the write events or poll the gatts value via the softdevice?
It looks like it's faster (+shorter = less consumption) to monitor...
Over the past few months I have worked extensively on a few different projects that all utilize the nRF51422. In some recent debugging of GPIO issues (both relating to SENSE...
As the title says, I am wondering when the new SDK will be released to support the nRF51822 hardware revision. It looks like the latest (v4.4.1) doesn't have anything new...

Hi, i'm experimenting RTC1 using the app_timer module (not using S110 soft device), and i find some problems onRTC prescaler. If i set values as stated in the datasheet, for...
Hi,
I am trying to run several applications sequentially on the nRF51822.
I have another microcontroller controlling the nRF51822 by SPI.
I init the stack, the services...
Hi, I'm just wondering if there's a reason that the example code is always initializing all structures through functions. Has it something to do with sleep mode and RAM retention...
Hello,
I have a couple of questions about sending multiple notifications:
I want to send multiple notifications (from same characteristic), is that allowed by...
Looking at the AN36 code, i notice that in the APP_SCHED_INIT define, for the argument EVENT_SIZE is used sizeof(app_timer_event_t) . In the meantime, the scheduler is used...
Hi guys,
I was wondering if the nrf51822 can listen to data packets being sent over by the nrf24. In the datasheet they say it supports nrf24 protocol. But what exactly...
