Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
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 folks,
I have checked the current consumption while connected on an average to be 325uA (with uC taking 4.5uA) so this mean almost 320uA being consumed by the nrf8001...
I have a general question about the RF frequency tolerance of Nordic devices in general. Is the following calculation correct?
Crystal spec = 16MHz, +/-50ppm tolerance...
Are there any plans to add boundary scan functionality to assist ICT testing? If not, are there any other hooks into the part that can be used to test during ICT?
Hello
I'm using a pstorage_register from pstorage.c to register two application storage blocks in flash memory. But I have situation that first module have 6 blocks of...
Hi,
are the GPIO pins broken out on the nRF51 Dongle configurable and can be used for SPI Slave tests? I have a running system powered by a ARM Cortex 4 (Teensy 3.1) and...
We have an early implementation of the v6 SDK DFU ported to support S310 on a handful of devices in the field and need to update them to a new bootloader and we'd like to...
Hi,
With the validation of the BLE V4.2 specification will Nordic be implementing the new features of the spec and if so do you have any idea of availability and dates. ...

Hello there,
I am using the experimental_ble_app_uart with S110 on nRF51-dk and receiving sensor data via 1MHz SPI every time the timer ticks = 100ms.
Data transfer displayed...
Hey,
I created a custom PCB with the nrf51822 that reads two sensors via TWI and transmits certain data over BLE. I can program the chip, print strings to the terminal...
I am having problems with th Master Control Panel (no response from master emulator). When I search devzone, I see an answer related to this question that says cloed because...
Hi,
I have application where I drive LEDs with shift registers. I need to send 14 bytes via SPI every 200us while I am in BLE connection. Timing should be exact as shift...
