I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.

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...
Hi. I'm using nRF52832.
I want to add LEDs. Can it drive 20mA for LED?
As I see the datasheet, GPIO pins have "High drive" function. What deos it mean?
I hope your reply...
Hello,
I am having difficulty downloading an application using the sample images provided. It looks like the application boots into the bootloader, there is a brief message...
Hi,
I modified the blinky_freertos example from SDK 12 slightly to perform the following:
I have one timer and one task. The task blinks a LED and then suspends. In...

Hi,
I am new in BLE and working on existing product. i am adding BLE functionality in the existing product hence having one host MCU on my board. My product will be in...
Hi There,
I am doing current measurements on the nrf52840 in sleep mode with no RAM retention and I am getting different values based on how I take the measurements. Please...
I am attempting to interface a Winbond flash device with the NRF52. The
datasheet does not specify the idle state of MOSI when reading from the device. However, I cannot...
We started with the default project that have no heap.
Added mallocs to the system and they seemed to succeed, without realizing heap was set to 0. They did not return NULL...
hello
we have custom board with Nrf52840.
i already test the uart code on nrf52840 dk..every thing is working great.
my custom board is connect to the nrf52840 dk with...
Hi
I have a PCA10040 V1.1.0 that my company has been using to flash test code onto other nRF52832 chips (I don't know the details, but it has wires attached to the debug...
Hello,
I am using the BLE_app_hrs_pca example and I was wondering whether or not the unit in which my beat rate is encoded (bpm) can be changed. I mean, I would like to...
From document seems bootloader in SDK v12/13/14 does not support HCI/UART transport yet. So have to use SDK V11 bootloader.
However the application is based on SDK V13...
