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...
Now we use the SDK V11 I2S sample program to collect data of digital microphone. We want to get the frequency of the sound and the dB value size.I don't know how to calculate...
Hi guys,
I want to know if it is possible to get started on developing applications for nRF51822 without using the evaluation kit. I want ot have a couple of breakout boards...
Hi,
I am testing that nRF52832 transfer QVGA still image from image sensor to phone as follows.
nRF52832(nRF52 DK) is connected with image sensor through some...
Hi All,
About DFU.
I want to know about UART DOWNLOAD for nRF51822 with S130.
Can I download the firmware via UART for nRF51822 with S130 ?
It's not OTA DFU.

I wanted to know what's the maximum data throughput if one device has both roles (Client/Server) working at the same time. I already saw the tables for the different SoftDevices...
Is there another IC I need to integrate into my board to allow the chip to be programmed through USB? Also, is the same true for programming OTA? I understand that I will...
Is there anyway to enable the UART on a NRF51822 to be 7-bit data instead of the default 8-bit?
Lowest level driver structure I could find is
NRF_UART_Type (nrf51.h...
I'm using Master Control Panel for PC to try to test bonding with MITM security on the peripheral I'm developing, and I suspect there's something wrong with the Master Emulator...
I am using the nRF52 in 2Mbps proprietary mode. I am running my own custom stack to maximize data throughput. There are no re-transmissions in my design. I have a loop of...
In sample code for central devices,, the BLE event handler, on_ble_evt() , handles the `BLE_GAP_EVT_CONN_PARAM_UPDATE_REQUEST' by accepting the request. Is it possible to...
On pages 49-50 on the nRF51 Product Specification, in section 8.5.2, there's a bunch of current consumptions listed for the Radio with the DC/DC disabled.
Do those values...
Hi there,
I was hoping to first pull the SD version and application version from the device before I attempt to send an update.
Are these values exposed anywhere within...
LAST EDIT AT END OF POST
We are using a custom board with an nRF51822 programmed with a modified beacon application (which worked several months ago). After opening MCP...
