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...
Is there any way of instructing the BDS plug-in which optional characteristics to include in code generation for adopted services without converting to a custom service? ...

Hi:
I come across a problem when I debug NRF51822. I don't know how to config its clock.My board XTAL is 16MHz, and I want config is to 32MHz，Is the method below OK?
NRF_CLOCK...
Hi,
My settings are:
NRF_DRV_SPI_FREQ_1M, NRF_DRV_SPI_MODE_2, NRF_DRV_SPI_BIT_ORDER_MSB_FIRST.
I'm trying to readback 0xD8. The proper value should be 0x71. Instead...
Hi,
I am trying to use the nrf52 in serialized mode, where I was successfully able to program the connectivity board (using SDK 11.0.0) However if I try to load any of the...
We are using a module which has nrf51822 on it. Before we have programmed it, we were able to see it when we scan for ble.
But after we program we could not able to detect...
I am building an automated test stand for programming our production devices. After programming, I need to pin-reset the device to leave debug mode so I can get an accurate...
We have an BLE application that we are targeting the nRF52 device for. The application demands using a UART interface to communicate to a host processor. In addition, we typically...
Hi all,
until now, I used nRF51 Chips on my board. I programed them trough the nRF51DK(PCA10028). But now I would like to work with nRF52832 Chip. I have a nRF52DK(PCA10040...
hi ..
i am new to mbed and nrf51.
softdevice is s130
if i enable the ADC in my project then other output(out3,4,5,6) is not working ok.
if ADC is not enabled then...
Thanks Stefan. The zip file making and updating steps work perfectly for me, if I follow your steps and make it from your stock pre-built "dfu_test_app_hrm_s132.hex". My question...
Hi
I have a problem when bootloading with nrf toolbox. It seems like when i flash files over 0x10000 in size the program overwrites itself. When i flash files with smaller...
I know this is somewhat "how long is a piece of string". I'm happy for guidance rather than solid numbers:
I'm trying to spec a "keep alive" circuit for an nRF51822 project...
