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...
I tried to work application.
But firmware stops at advertising_init(). When I exchange advertising_init() and services_init(), firmware does not stop.
why ?
S110 v8.0...
Hello,
My device is nRF51822 SD110 8.0.0.
The problem occured after firmware update in bootloader (own, not SDK) with readback protection enabled.
So bootloader connects...
Hello,
I am currently finishing my deploy script and I am currently using nrfjprog to write some custom UICR data. I have a contiguous region of memory to write but I do...
Dear Nordic team,
Beside other persistent issues with your proprietary DTM command for setting Tx Power (see here and here ) I've found that default Tx Power in ble_dtm...
How do I add multiple devices to a whitelist (as the central, adding peripherals), then use the white list for multiple connections? I have read both

I have nrf51822 QFACA1 and STM32f407VG. I'm programming nrf51822 QFACA1 using STM32f407VG SWD pings. And now I want programming BLE nrf51822 QFACA1 but I can't find any working...
I bought MOD-nRF8001 BLE Module for prototyping. I gave 3.3v Supply to modules's 3.3V pin & GND to GND pin. But, I cant figure out weather mODULE IS ON OR OFF. Its unrecoverable...
Hiiii
In our industrial product we are using nrf24l01+ on PCB which will be going to fully coat with epoxy material while manufacturing. My question is that , whether this...
I have modified the ble_app_hrs_c_s130_pca10031 example to run without external RTC and collect only battery status data from BLE peripherals that have a service with UUID...
Hello,
I tried the example ble_app_multilink_central (SDK 11.0) with S130 soft device. My requirement is that nrf-dongle should work in central mode and it should connect...
Super general question :)
Our current products use nRF24 chips (paired with 8bit AVR's) and we're very happy with performance.
For us the key requirements are low latency...
Hi all, i am trying to load this example on the smart beacon kit; i followed this guide step by step ( devzone.nordicsemi.com/.../) but the problem is the if i load the precompiled...
Hi all, i want to use the internal bluetooth of my laptop to receive values of a sensor on the nRF51 DK, and save them in a text file. How can i do this?
Hi, In my project I am using the signed bootloader example. The issue I got if I generate .zip file for dfu without --key-file the with --dfu-ver is option is working fine...
I have up and running the serialized ble_app_hts using ser_s130_hci serialization on two BMD-200 evaluation board of Rigado.
Now I want to know what files I have to use...
