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...
There are 10000 posts with this problem. I have imported someone else's project, and the file exists at Keil_v5\ARM\Packs\ARM\CMSIS\5.7.0\CMSIS\Core\Include exactly where...
Hi all,
I've been trying to get BLE up and running on our custom board after writing firmware on the DK. I am able to get other peripherals on our board up and running ...
Hi guys,
I am a long term Nordic user since SDK12 and i know that Nordic does not support MbedOS by any means but maybe you could help me try and understand what needs to...
Hello,
I've a very strange problem with the nrf52838 chip in the ISP4520 ( https://www.insightsip.com/products/combo-smart-modules/isp4520 ).
The nrf52832 advertise...
Hi,
I need to sample ultrasonic signal with PDM microphone. I would like to use NRF52840 PDM module and configure it for sampling frequency of 96KHz. Is it possible? Also...
Hi,
I have used BMD301 BLE chip. I have connected one wifi chip "ESP02" with BMD301 chip via UART.
I am using nRF5_SDK_15.3.0_59ac345 for my ble application firmware...
Hi,
we have a nRF52 DK getting sensor values from a Sensor connected as SPI-Slave. Everytime there is a new Sensor Value (~20 ms) the sensor generates an Interrupt and pulls...
Hi,
While upmerging our project from SDK 15.3.0 to 17.0.0 we faced an issue in the sdc_handler due to usage of a NULL pointer.
In the case SDC_EVT_INIT if the p_event...
Hello,
I am experimenting with PWM for time, I have a setup where I am using three sensor which gives analogue output.
I am using a mux which has two control pins, so...
Hi all
I have just started doing some work with the nRF52840- DONGLE (and hence nRF52840-DK) and am new to Nordic devices, tools, BLE, etc.
Basically for my first application...
I'm attempting to increase the size of the TX Queue in an effort to increase notification performance.
I'm using nRF52840 with an S140 soft device. I use Segger Embedded...
Hi,
I have two nRF9160DKs and I noticed that the SHA-256 digest of the credentials looks very strange
Questions:
1, Why are the digest so repeating? I have installed...
