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,

Hi everyone,
I am looking the schematic of nRF52840 (PCA10056) and I am a bit confused with the Power Sources (sheet 7 of 7).
There are three load switches that prioritize...
Hello,
My project:
- I have a low consumption project width BLE. - I'm using internal LF clock (I know it's better to use an external) - I use the Beacon example project...
Hello!
I am working on a FOTA solution for the nRF52DK, I have followed this example: https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs...
Hello,
I've started to develop with the nRF Connect VSCode extension and enjoying it a lot. However, I've noticed when I share a project the build configuration doesn...
Hi,
I observed what appears to be the same issue as https://devzone.nordicsemi.com/f/nordic-q-a/51337/nrf9160-infinite-nrf_connect-blocking-behavior-post-lte-psm-wakeup...
Hi,
I'm trying to write data to a characteristic. This is a BLE led driver. I can successfully send 5 writes and then it stucks. All the 5 sends succeed - I can see the...
Hi
I need to Send one character from mobile. based on the character I need to glow the LEDs which is placed on DK. How can I achieve this is there any sample available for...
Dear forum,
We capture audio via PCM (10kHz, 8bit => rendering a raw rate of 80kBaud) on a BM833 and would like to transmit the data (one way) to a paired device using either...
Hi,
NCS1.9.1, VSCode, nRF5340DK,
Without external flash memory and not use mx25r6435f which on DK,
how does MCU store data (such as a series of serial numbers)?
and...
hi ，i want write flash by jlink，eg：write val 0xaaffffff to addr 0x76000, only write 4byte.
but when i write, err "flash not erase" occurred，
I don't want to erase this...
I try to onewire communication for DHT11 but I couldn't it . I decided uart instead of onewire. The different microprocessor will read the sensor data and send it via uart...
Hi,
I'm trying to combine OpenThread, MCUBoot and LittleFS in a sample in nRF Connect SDK v1.5.1, but I'm getting the following error:
I have checked the file, and it...
Hello NRF Buddies,
My project is based on NRF51822 with SDK version 12.2.0. I am working with Keil till now and planning to migrate to the Segger Embedded Studio.
With...
I am not sure what I am missing in this. This is a custom board so there is no other circuitry on this pin other than a pad to monitor the signal changes with.
When...
Hello!
Regarding the CRC on the nrf52840 the specifications make it clear that the maximum length of the CRC is 3 bytes, We are working on an industrial communication protocol...
