Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
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.

Hi,
I've been trying to do fake non-connectable advertising with a nRF24LE1 with base on [1] and [2], they use nRF24L01+ with an AVR which I have ported to my device. I...
Hey,
I'm evaluating a nRF51-DK and face NRF_ERROR_INVALID_ADDR when trying to set a value in the local gatt server database.
My goal is to create a read-only characteristic...
Hi,
I'm using nRF51822 Beacon v1.1.0. Is it possible to detect that the beacon is being scanned? Is there any event generated during this process that I can catch?
I have been studying the ble_app_hrs example, but it has unnecessary functionalities, and it is hard to understand.
Do you have a simple application for transferring data...
