We are considering using Gazell for an outdoor application, i.e. lots of noise and disturbances, constantly changing environment, where the amount data being transferred is...
Hi everyone,
I have found your git "Ble Optiboot"( github.com/.../ble-optiboot) , and I have understood, it is usefull to load a binary into MCU flash, I was looking for...
I'll go ahead and describe what I need to do and see if anyone might have some place to start for me since I'm having a lot of trouble figuring out what I need.
I'm looking...
Hello ,
I'm designing an embedded system with one of your RF chips (NRF24L01+) and as far as I searched for the datasheet , It seems like NRF24L01+ doesn't have a hardware...
Hi,
This post is very old.

I have a nrf51822 chip and I'm using it as BLE and it exposes some service and characteristics and it is working...
Hello!
I set up a project using NRF24L01 and a patch antenna ceramic, the type used in GPS.
In fact, I tested several types of antennas, F, F inverted, GPS, Loop. But...
Hello,
I'm trying to create a PC application to read out some Ti Sensor Tag modules. I'm using a nRF51822 USB dongle and the Master Emulator api.
The nRF dongle sees...
I am calling the spi_master_send_recv in a ISR from a GPIO using app_gpiote.c It causes a hardfault on APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type)); Otherswise...
Hi,
The nRF Toolbox app on iOS crashes when opening user added files in the DFU. These files are added to the app via iTunes. The version of the nRF Toolbox is 1.7 which...
Hi,
We're producing a custom board based on the nrf51822 and would like to add a USB Serial chip.
The current contenders are:
a) FTDI 232R
b) ATmega8U2 ( www.arduino...
As the picture shows, I saw this softdevice_hex option available.
The error says, "require nRF_SoftDevice S310_Hex".
But where to this missing component.
My development...
Im sending an 8 bit int using my AVR controller as follows:
static uint8_t* dummy_heart_rate = 6;
aci_loop();

Are there any pins that I can NOT use for SPI on the nRF51822? I'm not seeing any notes in the latest documentation but would like to make extra sure before I spin a board...
Hi there,
Using mbed i have currently programmed an nRF51 DK to transmit data through a custom service with 6 read only characteristics. Is there a simple way i can alter...
Hello.
I cannot get my head around app_timers. After reading the docs, examples and answers on the devzone I'm still unable to get it running. The timeout callback isn...
I am trying to add SPI to the ble_uart_example on my nRF51-DK but when I try to debug my code debugging just stops (All "step one line" etc. buttons grayed out) at this line...
Hello
I'm using the nRF51 DK and I have a UART over BLE link set up between the board and a phone with the nRF UART app. I'm trying to get the board to execute a particular...
Hi,
I'm using nRF51 Development Kit to program the beacons. I've connected the beacon just like it's described in the last update of this thread using the 10-pin adapter...
Hi,
I just noticed that the nrf51822 doesn't have an eeprom and I already had the pcbs done. Can I use the NVMC to write USER data on the CODE (is it flash memory are?...
I am trying to do over-the-air (OTA) device firmware update (DFU) on a device with bootloader same to the "dfu_dual_bank_ble_s110" example in the latest nRF51 SDK . On the...
Hello there guys i been reading your 100 pg PDF for awhile now and im yet to understand or realize how is it that i add/place/create a payload or data to send/Tx via Master...
We are using Gazell to stream data at <=6mS intervals for very low latency wireless gaming peripherals. We'd like to have many of these peripherals devices (more than 24)...
