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...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Hello,
I am currently migrating from SDK12.2 with softdevice S132 V3 to SDK14 with softdevice S132 V5 and have a problem configuring device names larger than BLE_GAP_DEVNAME_DEFAULT_LEN...
I am using nrf52832_xxaa and I'm porting my device from SDK11 to 14.
I have found that new sections have been added in the linker file of the examples like sdh_soc_observers...
Hi,
I use SDK v13.0.0 with SD S132 and to debug my application I use UART0 on Putty.
When I use SPIS (0) (no BLE and no softdevice) alone I perform all functionalities...
hello：
i use timer1 to get a pwm waveform，when i use RTT to test it，the waveform is ok，but when i take out the RTT，and Remove the battery and put on the battery again to...
I've made a custom board with nrf51422-QFAC, which I can program with nrf51-DK. I'm using SDK 12.3.0 and SD130, which is flashed to the custom board.
When I program the...
I'm trying to setup logging with printf() over UART and I got totaly blocked by following realy strange situation.
Let's have following very simple log_test.c:
Then...
Hi. I'm quite new to nRF programming. I successfuly solved how to compile/link/flash the software onto nRF52 DK using just a simple editor (Notepad++), the ARM toolchain and...
Wondering if there are any example/reference implementations of a bootloader for the nRF51822 that support Device Firmware Update over both UART and BLE? We've got the BLE...
Hi,
I have met problem when apply dfu of nrf52810.
I used dfu sample of 52810 from devzone link: https://devzone.nordicsemi.com/f/nordic-q-a/28471/about-ota-for-nrf52810...
I met a big issue when implement the voltage level switch. I used nRF52832's SPI to communicate with an ECG sensor which has 1.8V SPI. The issue is that, 3.3V signal from...
Having just got the DFU functionality working I got the task of trying to add NFC functionality to the application. The code side was not a problem since I got a c and h file...
According to the BLE 5.0 Specification :
"The Link Layer shall use the primary and secondary advertising channel
indices as specified by the Host, and the used primary...
Hi,
There is a bug in a Linux box (Mint x64) with the following configuration:

Hi,
I am using ble_app_multilink_central and ble_app_uart central example for my application, i am combining these two example for ble_app_multilink_cenntral for BLE_NUS_C...
Hi,
I'm using the nrf_drv_twi driver (master) to communicate with a number of IO components, such as LEDs, buttons etc.
If my IO component does not respond (why is not...
