i am useing nRF51822 pairing with nRF24lu1 over GZLL protocol now,
is there someone have the experience on how to config the parameter of GZP_TX_RX_TRANS_DELAY in function...
I have a peripheral running the S110 stack, which presents a characteristic to which I want the central (running S120) to be able to do a long write. What I've been trying...
Hi all,
I have been trying to combine the UART and hID Keyboard examples into a single application.
I want to use the HID part to send specific keystrokes using buttons...
Hi, I'm new to BLE and just started feasibility testing, using RF8001, on a small device with no IO. The device will have a unique code set at factory, and printed on label...
I had the same experience as fishman and I went back to give Eclipse a try. (Post: nRF Beacon does not build on Android studio) I tried to build it in Eclipse Luna with the...
When using the BLE device, BLE_GAP_EVT_DISCONNECTED event informs us that connection between dongle and BLE device was closed/lost.
Is there a way to know when dongle connection...
When using nrf51-ble-driver_win_0.3.0 with Visual Studio 2010, after I put a breakpoint in my code, when I try to have the process "continue", I always get unandles exception...
Hi,
I'm close to finishing the implementation of a system with a recording device with nrf51822, working with 6 sensors with nrf24L01.
The recorder is in receiving mode...
I'm looking for an approach to RF coexistence between an nRF51822 bluetooth SOC and a WiFi module such as the WL1801. Does anyone have any experience or recommendations for...
Hi guys,
I tried to flash the pca10001\blinky_example onto a nRF51822 with nRFgo Studio.
Flashing the s110 worked fine. But when I try to flash the hex from the example...
Hello All,
I'm thinking a small plastic case for a portable device.
It is possible to place pcb board (with pcb antenna) above the battery (Li-Po) or can interfere with...
I want to log basic intermittent events and push them to a previously associated mobile device when one is nearby. The mobile device can then forward the events up to a server...
I'd like to know what is the minimum and maximum frequency I can generate on a GPIO with a 50% duty cycle (+/-10% at the worst case). Which resources should I use for that...
In my case active CE signal defines byte boundaries - for each byte individually.
From what I see, DMA seems to stop on rising edge of CS regardless what is declared in...
Hello everyone,
I'm using nRF51822 development kit to do BLE network experiment.
The boards I use are PCA10005 with omnidirectional antenna, and PCA10004 with PCB antenna...
I'm looking at the UICR hardware peripheral example , and trying to figure out the utility in writing to the UICR registers.
Why would I want to modify the compiled hex...
Very new, so please forgive the questions, but...
I have an nrf8001 that I've powered up. After initial power up, I'm able to read the DeviceStartedEvent but the response...
I'm looking to integrate a digital (PDM/I2S) MEMS microphone into my nRF51822-based design. I'd like some pointers to reference designs or other information -- the ones that...
Hi,
I would to know why when the DC/DC is enabled the current is very high (57mA) during RF sending.
Why at the end of RF sending the current is higher than...
I am modifying the bootloader. I am not using DFU or any of that, but rather copying a FW image over from external flash through SPI. The area of my code that gives me problems...
The documentation of the S110 contains sequence charts that explain how the different GATT operations are performed.
