Hi,
I want to send data from one peripheral(nRF51 DK) to multiple Android Phones. This will be a one way connection from the peripheral to the smartphones. I red on the...
I am working on "nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_central_and_peripheral\experimental
\app_s130_demo\pca10028\s130\arm4" project .
In this project,in which variable...
Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
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...
hts, HTC phone, nrf tools HTM, nrf51822,
every time when it's power up :
the once connect: error code 0x7A cann't read characteristic and 0x14 state change.

Hi all,
I am using ble mesh code, it has version based. For my application( needs to blink led synchronously in mesh) i don't need version part, so i tried with using if...
As your datasheet, External HFXO's Run current is 250uA, but HFINT case is 60uA.
Despite lager current, why do you use HFXO in reference circuit?
I would like to use HFINT...
using **nrf_drv_saadc.**c and nrf_saadc .c nRF52832 with sd132v2.0
for example.
i init a app_timer to update a adc channel per 10ms.
and manually update the batt volt...
Hi
I'm trying to send adc value from peripheral to central. I'm using nrf51822 with softdevice s130_1.0.0 and SDK v10.0.0 .
I'm getting error 3002 which I figured out...
Hi everyone
I am trying to understand if it 's possible to change the clock frequency on-the-fly, by giving a certain command to the uC via UART.
I started from the...
I am using esb in SDK 11 and my understanding is that the radio causes interrupts that are forcing and cannot be disabled. These in turn causes software interrupt 10 to be...
Hello,
I'm using nrf51822 with a few sensors and nrftoolbox app in my smartphone.
In nrftoolbox SW, I can just connect and see what happens in sensors.
I want to control...
I need to use Timer 0,1,and 2(I have only 3 timers 0-2 in nRF51822xxAA). This means, I cannot afford to let the BLE use a timer(I can certainly afford to give one RTC for...
Hi,
I'm trying to update attribute value and notify it to client using sd_ble_gatts_hvx() function:
memset(ms, 0, sizeof(params));
params.type=BLE_GATT_HVX_NOTIFICATION;...
When I use sd_ble_gatts_hvx() to send data to iOS and Android device I meet a problem:
Data send to iOS ok,but will return error 8 (invalid states) when send to Android...
Hi,
I am trying to use SPI to get data from a sensor. In nRF 5 SDK V11, I got it to work by setting the SS pin in the config struct of the initialization function.
...
I guess the answer is yes, because I know Characteristic Declaration (UUID 0x2803) has an unique handle for each characteristic.
Just wanted to confirm.
Its the first time I use simple_timer. I do not use the Softdevice. So I'm working with the peripeheral simple_timer example(SDK11).
I know from the app_timer, that every...
Hei!
I recently added WDT to my existing project. After that the normal behavior/sequence of code is not as it is supposed to. Strangely it works okay every other run now...
