First time here? Check out the Tour!
I set up eclipse according to n-AN29 and imported several of the example projects. The blinky_example project described in the nRF51822 dev kit user's guide works perfectly (I get blinking LEDs). When I try to use the heart ... (more)
I am looking for details on the internal temperature sensor on the nRF51822. I would like to use it to get a general ambient reading of the air around the device. Basically, I need to know if this temp sensor ... (more)
hi everyone.now i am developing a project with nrf51822.i am using the PCA10000 dongle to see some information of advertising packages. i moved out and pluged in the PCA10001 many times,but the random address are the some ... (more)
and can user change it?or the hardware does not support BLE_GAP_ROLE_CENTRAL?
i searched many many times,and i can get the anser.what kind of GAP Address type does BLE_HRS demo use.can someone tell me?tks!
I tried changing the define below from 1 to 2, so I could have one handler for a button and a different handler for other sensors. But my problem is: 1. If I set it to 1, the button handler ... (more)
I get following message when I try to program with the Blinky project a nrf51822 chip: "Error - flash download failed - Cortex M0.
What is wrong?
Hi, I have been trying to maximize the baud rate of my uart module, I am using the app_uart layer to control the uart and I have noticed that in your implementation of HCI you have set the baud rate ... (more)
I've developed a circuit with Mikroelektronika's nRF T click module. This module uses nRF24L01P but as I see I cannot order it because it is obsolete.
Should I use nRF24E1 or nRF24Z1 instead of it? In our ... (more)
I have a couple of questions about sending multiple notifications:
1) I want to send multiple notifications (from same characteristic), is that allowed by S110 softdevice?
2) What is the maximum number of packets that S110 could process per ... (more)
Hi, got an interesting problem, this is on a custom board with nRF51822 QFAB that we are bringing up. The radio test (not using softdevice) works ok and produces strong transmit signal (as strong or even stronger than from the ... (more)
my application is a 9-axis battery driven motion sensor with a data rate about 144 bit per packet at 1000Hz i have to transmit over air. Low latency (<10ms) is extremely important. The device must consume as low power ... (more)
I have an ultra low power application that needs to broadcast it's proximity on a 1sec interval. However, about 75% of the day I would like the device to be powered down and not transmitting.. This should be controlled ... (more)
I'd like to use 'Direct Advertising' to get the attention of a Central (a specific one or any in range) when an event happens on the peripheral. Is this mode supported by the device / S110? If so, is there ... (more)
Why some devices makes just an IRK entry in Whitelist of SDK and other put the address into? Is it possible to config which entry should be done?
How are the four RAM banks divided up in the nRF51822? Is it an even split of the 16K total RAM (i.e. 4K per block)?
Furthermore, can I expect strange results if I turn on RAM-retention for the 8K ... (more)
My question is how to configure clock in gazell protocol on nRF51822
I look at the example gzp_dynamic_pairing but that does not have a code part of modifying clock.
I know defining SystemCoreClock on "system_nrf51.c" and i ... (more)
My target board is nRF51822, and I want to run the heart rate demo project, but a error message when I compile it :
[b]Build target 'nrf51822_xxaa_s110 (256K)' assembling arm_startup_nrf51.s... arm_startup_nrf51.s: error: A3903U: Argument '--pd' not ... (more)
I need a mutex and I found this information at the ARM site: http://infocenter.arm.com/help/index....
Is there anything I should be aware of in using this technique to implement a mutex?
I would like to build a tool in Python that allows sniffing/interaction with BLE traffic between nRFgo modules (nRF51822) and a Mac via the master emulator. I am looking for an alternative to using an iOS device simulator ... (more)
I want to get RSSI between PCA10001 and PCA10000. As you known, I have to make these two device connected first. If I write my code based on the example of UART, are these two device connected? What is more ... (more)
I have download the given software about UART to my nRF51822-EK. But it didn't work. Do I need s110 or not?
When I use keil to download the software to the chip, there are two questions: 1. like attached. 2.NRFGO CAN'T SEE J-LINK LITE CORTEXM BOARD Is there any way to solve these problem? Many thanks
hi, Now,my pre-Develop product(BLE),that to measure the Tx transmit power not correct with my setting(default 0dbm). so,i have program a project for to sure the reason(Hardware or others)?
Have a project for measurement transmitting ... (more)
I have been experimenting with the master emulator .dll - I started with the HidDemo project which is written in C#. This seems to work perfectly well.
I have rewritten ( translated ?) the demo code into VB.NET ( Visual Studio Express ... (more)
how can i change that my programm doesen't go to power off mode? I use the ble templete.
Best regards Nils
i need to handle a button detection Time, i mean when i push the button for 2 seconds something should happen. How can i use the app_timer_cnt_diff_compute function for that?
Best regards Nils
Can someone point me to sample code exercising the quadrature decoder found on the nRF51xx series (or something similar). Thanks!
I a writing my own interrupt and DMA based code for sending commands and getting events from the nRF8001. The 8001 creates an event for every command, but if you want to clock out an event with dummy MOSI data ... (more)
As stated in standard the maximum data rate is 0.27Mbps. So is that is true for nRF8001 ??
