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...

Hello,
I have been messing around with a PCA10001 Dev board trying to do some power consumption tests (Beacon demo code). When I enable RTC1 only and use __WFE in the main...
Hello everyone,
I haven't read anything in the official documentation about it, but I was wondering if the S110 has an embedded checksum that I can use to verify its integrity...
Hi,
I'm currently working on nrf51822 beacon connected with stm32f4 board. able to communicate fine on UART as well as with bluetooth device. is there any way to find out...
We have been using the nRFgo nRF51822 development kit for prototyping. We now want to design our production board. However, your site says that this dev. kit is not recommended...
It seems these functions are identical in what they do, except that one is in S120 and the other is in S110.
Why not standardise the booting mechanism to facilitate code...
Hi !
I'm developing a bluetooth low energy service using the nordic evaluation kit and following the ble_lbs example. It works, but when I load the code on an other electronic...
Hello,
does the iOS Loader app not work with the nRF51422 chipset? I thought that this chip was more capable than the nRF51822. I do not seem to get access to the download...
I'm concerned about stack overflow as I consider using a linear fit function which declares 5 local variables as floats and accepts 5 pointers.
5floats * 4B/float + 5pointers...
Hello! Can anyone tell me information about bluetooth protocol and SDK functions?
What functions need to start BLE device like a peripheral/central, and what each...
