Hi,
I am using the NRF8001 in UART mode and attempting to bond with my android device (Lollipop 5.0 Nexus 6).
i am using the nordic arduino sdk which is found here:...
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...
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...
I have a nRF51822 module programmed for custom service and characteristics. I am able to connect to this module using android 4.3 API. I can get characteristics and their...
First of all, let me say that I've read some of the other topics, and I clearly don't belong here haha. I'm not at all knowledgable about electronics and the inner workings...
I wonder if a couple (or three) of your module with PCB antenna as receivers could be used for triangulating the transmitter, could I have some hints about this, or a schetch...
Just putting this here in case anyone else comes across this issue, esb_arm.lib and gzll_arm.lib don't appear to implement the work-around in PAN 18(in the version I tested...
Hello, I would like to know if the adress byte that is transmitted after the preamble is the MSB or LSB.
I've read the datasheet's page 28 and it's not very clear, it just...
I need to have an iOS device send my nRF51 some commands, some settings, and retrieve some data, not at regular intervals. The nRF51 should only-speak-when-spoken-to.

Hi guys,
I want to use the nRF51822 as a gateway to send uart-commands from the µC to my iPhone and vice versa.
