Hi, I'm using the nRF8001 in an application that requires security so bonds to the remote client/central. My device supports firmware upgrades that may involve new nRF8001...
Hello.
Initially when reading the Gazell documentation I didn't think it'd be a problem but now in Keil seeing this has introduced some doubt whether it's a thing:

We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.
At...
Hi,
I'm trying to program nRF51822 Beacon Kit using nRF51DK. I'm trying to load the example ble_app_beacon to the beacon kit. After uploading SoftDevice 7.1.0, I try to...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
Hi expert,
I am developing 51822 under SDK 6.1, and we have one button and some sensors' interrupt lines as input GPIOs in our platform. In my code, after calling gpiote_init...
Hi there,
I am trying to send six 20 byte packets per connection interval. Is changing the length of charecteristic simply

I transfer data through UART for nrf51822-EK(PCA10001).
But this time. I used nrf51822 smart beacon...
I develop with nRFgo SDK 2.3.0.10040.
Normally PRX can communicate with PTX by auto ACK, but when there are two or more PRXs with same configuration exist, once PTX sends...
Hi all,
I am trying to use for the first time my nRF51822 development kit, following the "Development Kit User Guide v1.3".
The problem is that when I open "nRFgo studio...
Do all revisions of nRF51 have the same 4kB RAM sections with separate RAM AHB slaves? The product specification clearly states that only for revision 3 chips.
Not really a question, but it took me way to long to find out about J-Link RTT (i.e. j-link Real Time Terminal for easy debug printing so I thought I would mention it for...
I need a fixed voltage reference on my circuit. Since nRF51822 has internal 1.2V voltage reference, I am just wondering if there is a way to use this reference for external...
Header for nRF51 (nrf51.h) mentions two peripheral blocks completely missing from chip documentation. Are they functioning? If so, the comment for PATCHADDR field of PU says...
Hi there,
After prototyping a device with modules and on a breadboard, I transitioned to a custom PCB with nRF24L01+, matching network from the spec sheet, and 2.45 GHz...
