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...
Hello .
We have an issue with the SPI channel.
We found out that when our GPIO config as SPI the CS drawn a lot of current when it connect to the slave device device AD7770...
Hello,
I am working on pc-ble-driver-py to design a central (using a DevKit with a nRF52832). At this point I am trying to perform a phy update procedure but I see it is...
Hi Everyone,
I am using PSM mode in my program and want to send data everytime when modem wakes up from sleep(PSM mode). I also want to turn off/on UART only when required...
Hi,
During startup the nRF sniffer extcap script does the following:
Which (at least on Linux) breaks applications having open serial ports.
Why not instead use...
Hi all,
I have mqtt sample on my board, after I added MCUboot module from Configure nrf Connect SDK Project, when I try to debug, it gets stucked at :
#elif defined(CONFIG_ARMV7_M_ARMV8_M_MAINLINE...
hi,
nrf52840 BGA footprint P0.22 config as UART0 RX mode, don't receive any data, but config as other pin P1.06, work normally.
and I also test QFN footprint with nrf52840...
I have nrf52832 platform and my version of softDrive is (nRF5_SDK_15.3.0_59ac345). I red a lot of documents and tech support like these links but couldn't find my problem...
I have another MCU on the same board as the Nordic 52832. The firmware update image for the MCU is about 50kb in size, so instead of adding a parallel DFU for the MCU through...
So currently I am using a 5 second repeated timer to run all my operations but there is a draw back to this that the max accuracy I can achieve is of 5 sec, like if I want...
Hello!
I have 18-bit sensors with SPI and I2C , which I intend to use in a wireless array.
I need to choose equipment and topology (star, scanning mode?), enabling data...
We had a custom board made with the nrf9160 and I noticed I was having trouble communicating with the sim card on my board.
We have been testing i2c, spi, number of peripherals...
I am trying to run the hci_uart sample on my 9160 DK but I am facing problems uploading the code. I am able to run the AT client and Asset tracker just fine. As soon as I...
I've been attempting to optimize my scan and connection intervals in order to maintain the highest percentage of time scanning while maintaining connections, following the...
Hi,
I am developing a Linux PC application (central) connecting with nrf52840 dongle with s140 v7 flashed on it (for long range support). I am using pc-ble-driver v4.1.1...
Hi everybody,
I'm having a problem with the advertising function of the SoftDevice.
When the application starts advertising the function "sd_ble_gap_adv_start()" returns...
