First time here? Check out the Tour!
It is not transparent to me, how can I determine this value? Is it a best practices value? I want to implement Tx Power profile but I don't know where to get this value.
Another question is, how ... (more)
On top of almost all the BLE examples in the SDK, there is an APP_TIMER_OP_QUEUE_SIZE define. How can I know how big this should be for a specific application?
I'm leveraging off the heart rate sensor example to create my own VS service. I've successfully registered a 128-bit UUID with the Soft Device which is enumerated along with 0x1800, 0x1801, the Battery Service and the Device Information ... (more)
I'm confused about the use of these two functions. I want my app to sleep immediately upon start and then wake up and do a BLE advertise when I press a button.
1) I see that both of these ... (more)
See subject. The softdevice is currently installed on the chip (v6.0.0-1.alpha)
I searched online, and found some information that the security state of the chip has been set to "locked". Is this true? How to unlock it?
Hi Nordic devzone,
For the nRF51822 device, I would like to know if there is any internal pull-up/pulldown resistor on SWDIO and on SWDCLK (although a 12 K-ohm pulldown resistor is required on board). Also important is to know ... (more)
Hi, I am trying to get the rssi value of a connection, and what I am trying to do is to start the rssi in the beginning at the connection and end it at the end of connection. So in ... (more)
I'm using the MCP to send a long to a nrf6310 board loaded with SD v6. The board hangs when I send a long though, is this due to the MCP not being set up to send longs ... (more)
I have a question....
I have real ECG device and I almost got PCA10001 development board. Studying about PCA10001 I noticed that this board has ADC. I downloaded aplication nRFready iOS demo App from Nordic Semiconductor to my iPhone ... (more)
I have a system that uses 5-byte addresses. The first 4 bytes are always the same, but the last byte has 4 different values. For test purpose I want to listen, from another unit, and without sending anything, to all ... (more)
Is it possible to give a function address to the "Task End-Point" of a PPI channel?
err_code = sd_ppi_channel_assign(PPI_CHAN0_TO_TOGGLE_LED, &(NRF_TIMER1->EVENTS_COMPARE), &(myTestFunction));
Or the only accepted TEP are timer and GPIOTE tasks?
in my application I have a device that has to be controlled by a remote control. For transmitting data between the remote and the device I would like to use BLE (not the proprietary Nordic protocols).
1) Is it ... (more)
i get the example for using PWM to run and modfied it to use it in my application. My Prolem is that i only have one PWM Output toggle Pin. How can i build a second PWM output, i ... (more)
if i dont wana use windows to do this.
hi,i wana use iap for nrf51822,so it can firmware upgrade like ti's oad,is nrf51822 have such spec?
does nrf51822 support the function of cortex-m0?i cant see any document about this
I know that nrf51822 is not supported system tick handler ? I need system tick function. How can i make system tick function for nrf51822?
do you know of an explanation or some kind of tutorial to see how Bluetooth Low Energy works? For example some detailed information on those nrf51822 examples. What is definately needed for running BLE, and what is not ... (more)
I am designing a device that needs to operate both as a Peripheral (such as a Heart Rate sensor) and also as a Central so it can optionally connect and gather data from other Peripheral devices. Is this possible with ... (more)
Do the softdevice stack support wireless firmware update through BLE?
Thank you! Joseph
Your served radio tramsmitter/receiver example using PCA 10000 USB dongle, PCA 10001 evaluation kit. It's just only one byte data communication. It works well. If I communication multi-byte data with one packet, what did I fixed source code ... (more)
Your served radio transmitter/receiver example using PCA 10000 USB dongle with PCA 10001 evaluation kit. There is only one-byte send/receiving example. So, I was to send(receive) ten-bytes in one-packet, I changed source code "main.c","radio_config.c ... (more)
Can you tell me Using built-in flash and use restrictions,
because it halt at ble_flash_page_write() function.
Recently i have bought 4 nRF51822 custom board and unable to program it. The laser mark of the nRF51822 for custom board is N51822 QFAAC0 1308AE
I failed to program with the firmware that function properly on the nRF51822 Dev ... (more)
I'm attempting to write my own Service based on an example; there are two simple Characteristics in the design. During the discovery process, however, I'm getting the following:
... [16:16:23.6] Received Read Response, handle: 0x0007, value ...
I'm confused about how to assign a functional block's I/O (TWI in my case) to a particular pin on the device. Is there a worked and documented example? Is there a relevant application note?
Now that I have TWI and the BLE stack initialising, I'd like to create services. The Server (peripheral) sends out a few bytes to the client when a local trigger happens, and also needs to be able to accept ... (more)
I'm looking at the led.c example in the heart rate monitor example. What this shows is how to tie a TIMER event to toggling an LED. I understand most of the mechanism there. The novice that I am ... (more)
What's the proper way to implement bonding that depends on proximity (rather than a whitelist)? So when the client (phone) is close (say, five to ten centimeters) to the server (BTLE peripheral) then there is a bond created and ... (more)
