Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
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...

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...
Hello,
I want to prevent a scenario where I successfully perform a DFU with a faulty firmware image. I have a bootloader that handles firmware updates both for the NRF5...
Hello all,
I am working on low power sensor development with nRF52833 as target. I have some questions but I'm not sure it this was addressed in some other posts.
1. I...
Hi,
I'm integrating some c++ code using ble_app_uart example as base. The code has some cout << "text"; kind of outputs that seem to go to uart by default configuration...
Hi. I'm trying to find out the real consuption of the nrf52832. I have two questions after consulting part "7.2.1 CPU performance" of the datasheet.
1- Is there a difference...
Hello,
I have recently used the new toolchain manager to upgrade to ncs v1.3.0. Now I am using Segger Embedded Studio to flash an nRF9160 with the at_client sample. My issue...
Hi ,
I have an Android app that acts as a Central mode and Nordic nRF9160 as peripheral mode.
Once the connection is established , App will read the characteristics...
Dear all,
Pushing the hardware to the limits, I came up with a question about the architecture of the microcontroller itself: Can two different instances of SPIM start...
Hello,
I am experiencing some strange behaviour through DFU process when build with GCC -O2 optimisation.
The upgrade process seems to complete successfully but after...
I got a device with a secure bootloader, but I lost the private key and the firmware got corrupted somehow. Is it possible to flash a new bootloader via BLE or is it bricked...
I am trying to understand the following, hopefully someone can explain:
AFAIK, BLE advertising is stopped as soon as the limit of the SD is reached, AKA the PERIPHERAL_LINK_COUNT...

Hi Support Team,
We bought the nRF52 DK along with the PPK so we can measure current consumption of a DUT. It was working on the power profiler App in nRF Connect and we...
I am starting up with nRF52840, currently i have the dongle but expected to receive my DK in the next few days. This is my first BLE project, so i started reading a lot of...
