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...

Hi Nordic's community,
I have a question about how to write values to different characteristic in one time ( the values to write are inferior to 2O bytes) with an Android...
Hi
I've implemented a BLE peripheral based on the SDK11. For bonding i'm using the new peer manager. If the code runs on a nRF51 DK the bonding works properly. After the...
Hi
I'm having problems with the I2C. For now what I see is the twi_transfer function remains in infinite loop. Other symtomp is the SDA line remains normally at low level...
Hello,
I am currently trying to transmit around 800kbps of data using the Nordic ESB protocol. I am also attempting to sample 2 inputs using the SAADC at around 32 khz...
Hi,
We try to communicate between nRF51822 SoC and a GPS module through UART on a custom board but failed initializing UART.
More details:
We use nRF51822 as a...
Hi i use a soft with DFU and Beacon.
I will use the beacon and when i press on a button i can update the software with DFU.
DFU and BEACON works independently but when i...
Hi. We are going to mass production now and the 3rd party lab that will certify our product says we need to have a special mode in the firmware that would do :

Hello Nordic! Regarding Notifications on the s110, once sd_ble_gatts_hvx(conn_handle, ¶ms) returns NRF_SUCCESS , how long does it take, at most, in units of CI (Connection...
Dear sir.
I have question of SPI slave communication.
[NRF_SPIS1->TXDPTR] is a point to address of TX buffer.
After [spi_slave_buffers_set] is called and SPI transaction...
I've successfully compiled, flashed, and run the SDK11 ESB examples on nRF52 DKs using GCC, and am trying unsuccessfully to get them to work on the Keil 5.20 IDE.
I've...
I tried to get the ble_app_proximity example to work today, with either the nRF51-DK, nRF51-Dongle or nRF52-DK, along with the Nordic Connect app on Android.
I encounter...
