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 Guys,
I am new to the nrf52 family of chipsets and started my work with a custom board containing the nrf52832 chip and some on board peripherals like GPS and some sensors...
phenomenon:
When master successfully encrypts using previous binding information, pm_evt_handler in main.c receives a PM_EVT_CONN_SEC_SUCCEEDED event and gets a bonded...
I want to read and write certain pages from the NRF52 flash via nrfjprog. The goal is to debug an issue with the peer manager by saving the FDS flash contents to disk. I would...
I have downloaded the Eddystone example to my nRF52832 dev-kit and I am trying to register it with the google beacon platform using their beacons Tools app but it says that...
Hi,
i have the below queries:
In our project we are using multiple masters and multiple slaves, in that each slave is dedicated to a single master.
for ex: we are having...
Hello. I created some HID device based ble_app_hrs_pairing_nfc example on NRF52. And I have a questions:
1.I need to automatically reconnect to bonded device after reboot...
By default, the NRF_DEBUG is disabled. After enabling, and removing this assert check:

Reading the documentation online for the BPROT component for the nRF52832, it seems like resetting is the way to clear the Write Protection bits in BPROT. Is resetting the...
I'd like to be able to change the ble connection interval during during runtime to save power. I followed this post and found that p_ble_evt->evt.gap_evt.params.connected...
Hi,
We like to develop a battery powered device with small current consumption which will communicate with mobile devices over BLE. It will comunicate with mobile device...
Hello Everyone,
It is unclear to me how a soft-device operates regarding multi-tasking and event-handling. I'm assuming Nordic engineers have their own real-time operating...
Hello, i wanted to ask if NRF51 Dongle NRF51-Dongle is capable of sniffing packets from NRF52xx parts? If yes, what are the limitations, because i think that nrf52xx parts...
Below linked blogpost says,
if using a PCB antenna, the matching network should consist of one shunt component.
