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...
Hello,
I am designing a custom 2layered PCB board with NRF52832 IC. I have followed the reference design given in IC's datasheet as shown in the figure. Please provide the...
Hi,
I'm currently building a BLE multi-sensors device, with mbed online IDE. I succeed in implementing BLE API, and releasing a first .hex firmware with multiple services...
Hello,
I added an extra opcode to the DFU Control Point characteristic so that I can jump to the main application by writing to it. The problem is that whenever I do that...
Hi there,
quite a beginner here and tring to figure some stuff out about the nordic programming style.

HI,
I got 2 nRF52840 dev kits and I'm interested in testing the long range layer (LE coded PHY ) between the 2 modules, also scan for the second module RSSI value.
I...
Hello,
This is my first time working on BLE and Nordic, so this might sound strange.
I am trying to update data on the fly when the central requests char data.
I have...
Hello,
I am designing a 2 layer board with NRF52832 IC. I am following all design considerations and reference design mentioned in IC's datasheet provided by Nordic. I have...
Hello,
I am designing a PCB with NRf52832 IC. I have a query regarding the width of the feed line. In reference design files, the width of the feed line is 30mil. I have...
Hello,

Hi,
I have designed a custom PCB using NRF52832 IC.I have followed Sparkfun NRF52832 breakout board for placement of NRF52832 IC core part(including antenna) which is similar...
Hi,
I am using nRF52832 with NUS and buttonless DFU running well next to each other (SDK13). Instead of the standard way to jump to the bootloader (writing a 0x01 to the...
We have a device running SDK 11, without a crystal. It was using:
#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC, \
.rc_ctiv = 16,
.rc_temp_ctiv = 2}

Background:
In a previous posting I had asked if anyone knew of BLE connection parameter guidelines for Windows 10.
The general response was, yeah ios has BLE connection...
