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...
I use a 3.3V battery as VDD on an nRF52832 device.
Along the line this battery might do down from 3.3V to 1.8V. Will the Internal Reference Voltage be consistent at 1.8V...
Hi,
In apply_old_config.h ,here is the code:
for example:
If I set SYSTICK_ENABLED =0 in sdk_config,here will overwrite the macro define because #if defined(SYSTICK_ENABLED...
As per the datasheet of nrf52840 any peripheral like SPI/UART/... can be configured to any of the GPIOs so is the QSPI also.
But at Pin details QSPI pins are recommended...
Hello,
We are working on machine health monitoring system. For that we are using nRF52840 SOC as Central and nRF52833 SOC as end node. We had used single Central node and...
Hello.
I'm beginner on Nordic product and checking the examples with nRF5_SDK_17.0.0_9d13099 on nRF52833 DK Board.
I tested ble_app_uart and it works. Now checking ble_app_hrs...

Hi,
I'm trying to find a way to power down and on again a RAM section, but I haven't had any luck finding.
In the SDK examples, there's a RAM retention example only, but...
Hi! I am using nrf52832 with icm20948 (SPI) and I want to put nrf52 in sleep and wake up if there's any motion detected. I am unable to put my device on sleep by the function...
I use nrf_libuarte_async from nRF5 SDK v16.0.0, without softdevice on nrf52840. The idle power consumption of my board is several tens of uA. I call:
and then the idle...
nRF52840, SDK16.0.0, S140v7.0.1
We use SoftDevice (RTC0) and app_timer (RTC1). I'm trying to configure RTC2 and TIMER0 to do PPI-driven crystal timing as described in...
I'm using the empty_app_core project for the APP CPU and my NET CPU binary does not start. I suspect the NETWORK.FORCEOFF is holding the NET CPU in reset upon startup. I tried...
I have encrypted 12 bytes on the nrf51 and sent this + 4 byte MIC across to an Android device.
However, when I try to decrypt on Android using a Cipher with "AES/CCM/NoPadding...
Hello everyone,
I would like to developpe my own custom board, I would like to know if it's simple to replace micro USB by USB C and if someone has already do that to help...
