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,
I need to enable an input interrupt on nRF52832 and I want to use a GPIOTE EVENTS_IN channel.
During boot configuration, I'm using nrfx_gpiote_in_init function with...
There are two NUS services here, but only the second one can send data through the RX characteristic. I've checked the source code and nothing has changed. How do I delete...
Hello Nordic support team,
Forgive me if I am asking a stupid question.
In the source file ble_conn_params.c, there is a function called ble_conn_params_init() and I...
I am working on a wearable GPS tracking device using the nRF9151 DK and testing the GNSS example code. However, I am facing an issue with the cold start time for acquiring...
I recently bought a fanstel blg840 device, and I have programmed At client firmware in nrf91 and custom code into nrf52, but the problem is nrf52 is sending at comments to...
Hello,
I'm sure you know this already, but there seems to be a problem with the subject footprint. I guess I'm posting this to confirm that it in fact does have a bug in...

Hi,
We're planning to design a custom board using the nRF9151 for LTE connectivity. We'd like to add basic BLE support, with the following constraints:
The BLE chip...
Hi, I want to achieve high speed data transfer between NRF7002 DK with other development board. Therefore, I want to using SPI4 with 32MHz speed. However, I found out that...
I am currently developing a firmware application on the nRF5340 where I need the device to function in dual role :
As a Bluetooth Mesh Node , communicating with other...
Due to production requirements, I need to obtain the device's QR code. However, I found that the QR code can only be retrieved using the code snippet below after calling Nrf...
Dear Nordic
I use nRF5 SDK BLE_Central / uart to connect our custom peripherals by address, and I found that it seem need to 4~5 seconds to finish connecting
Here is the...
Hello, I have an nrf52840 which is acting as a central. I have a peripheral device which I can connect to, and the service that is discovered has the following table:
