I will be selling various ble products. My customers can connect to and program the devices using their bluetooth smart phone or tablet.
I want them to have the option...
Hi,
I am trying to run nRF24L01+ in default configuration using simple ping-pong examples using RF24 Arduino library.
The problem is that while ping-pong is getting through...
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...
by set a char with BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS, means it can't be read and write, if so, why not remove the char?
any reason behind BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS...
Is there anyway to limit the number of channels a device is advertising on?
I'm using an nrf51822 with the S110 stack and want to limit my device to a single advertising...
Hi,
We want a throughput between a BLE link 12KBytes/s.
In our application there is a peripheral (in Nordic starter kit), running S110 and we have configured connection...
I have two questions.
Is it possible to use the DAP[n]/DAB[n] registers without using Bluetooth 4.0?
If it is possible, then how? I searched all the sample...
I am starting with Nordic nRF51822 and I would like to know if do you have some samples for use with emIDE (I liked it because you don't have size limitation). And I had some...
I saw two different way to ini ble
1 ) BLE_STACK_HANDLER_INIT
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false);
err_code = softdevice_ble_evt_handler_set...
I'm right now getting uC to sleep WHEN THERE ARE NO ACI EVENTS I think I'm doing right, the uC sleeps but I'm not able to wake up despite the fact that RDYN is connceted to...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...

Hi!
I wonder what is the GPIOs nominal voltage level when I'm using the internal DC/DC converter?
I know that the internal DC/DC converter output voltage is 1,9V but I...
Hello,
we made PCB based on reference with ST balun. In circuit the low freq crystal is optional, so we didnt use it. In software i noticed app_timer use RTC timer. So the...
I am trying to bootload an extremely large hex file using a slightly modified DFU (modified from SDK v5.2.0's example)
The problem is that the hex is so large that eventually...
Im having errors like Arduino is in the while(1) loop if I enable the DC/DC converter in the characteristics and generate service.h file , If I do not use this setting everything...
