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...
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.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
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...
HERE is the fix for this problem. It has been reported before (by others) with no reply. I hope that this fix or its equivalent will be incorporated into the next SDK release...
I want to interface a 16MB external flash (SPI) with nrf52832 on the development board.Suggest me how should I start with and if there is an example for external flash then...
Hi Great Support Team:
In the spec of 52832, the rx sensitivity is -96dBm @ 1Mbps.
I'd like to know if the sensitivity is the same (-96dbm) while we adopt ANT+ protocol...
I am using the nrf52840 with freertos and bluetooth (based on the HRM example). Application is designed to sleep for a set period of time before the RTC timer wakes the MCU...
Dear Nordic Team,
Due to a mistake i flashed a bootloader-firmware with the compile flag CONFIG_GPIO_AS_PINRESET onto a custom board where pin P0.21 is tied to ground ....
I just received my nRF9160 DK. I got it connect with the nRF Cloud (with LED 3 and LED 4 blinking). I then started nRF Connect (Programmer) and the application crashed. I...
Hi all,
I want to ask whether I can put the main app on random address in the flash of the chip if there is bootloader and SD present due to future releases of SD and memory...
Hi. My application is scanning ble beacons for 1 sec every minute, and I want to store this data in an array to be sent every 10 min. I am getting the data in BLE_GAP_EVT_ADV_REPORT...
Hi,
I want to implement a Peripheral (GATT Server) that automatically starts notification once a Central connects. No bonding is provided in our system (connection is between...
Hi,
I'm in the early stages of developing a BLE peripheral device that requires the use of the CC310 CryptoCell on an nrf52840-DK board.
I have managed to implement a...
Hi,
I am following the midi service example: https://www.novelbits.io/bluetooth-gatt-services-characteristics/
To add a midi service.
I have added the code and build...
Hi,
I've been though some power profiling investigation of my application and incorporated the solutions discussed and here and the hardware solution discussed here but...
We are using nrf52832 in our design. It involves two nrf52832 with a bunch of sensors and one more nrf52832 which has cloud connectivity. We store the sensor information in...
