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...
I need to drive a stepper motor without software intervention, since strict timing is a must.In the following image you can see the required wave-forms - the motor requires...
The SD API (S132-6.0.0) documentation provides little beyond what one could guess from the function and type names. sd_mutex_acquire says "Attempt to acquire a mutex". nrf_mutex_t...
Hi i am doing a prosject to get notification on cell phone when i get mail in my postbox (postbox outside the house) I am using a nRF51 dongle, and want it to connect to cellphone...
Hi! I'm working on HID mouse example on SDK 13.0.0. I'm supposed to use this as a low power media button control. I've done a few modicifations on the code for power optimizations...
I know that few companies choose to use NRF528001 with a separate microcontroller like Fitbit.
I would like to know why would they do so instead of using an NRF52 chip that...
Hey,
I am using a nRF8001 with a STM32L051 as an application controller.
After resetting the nRF the RDYN pin goes low, as expected. Then I'm setting the REQN line LOW...
Hello all,
I have a Nordic Thingy 52 board, and I have download the Thingy 52 SDK, I can debug it successfully.
But after I debug it , or download it, the board runs with...
We have an application with FreeRTOS. If we do not initialize softdevice, the freertos interrupts tend to come in at a very very slow rate. I know that softdevice does clock...
nRFgo Studio displays a "Enable reset pin" option on the nRF52 DK but does not display this option on our custom hardware; we use a Segger J-Link for programming the custom...
Hello,
I would like to know the CALIBRATEOFFSET function in detail.
Could you disclose the part of source code on this CALIBRATEOFFSET function?
Best regards,

Hi,
In production line, I was supposed to do BLE test using DTM with UART interface and MT8852B from Anritsu.
However, the antenna is specifically tuned for plastic...
Hi,
i was about to solder my PCB that contain an nRF52832 and i've noticed that i didn't have C9, C10 capacitors.
C10 is the 1uF decoupling capacitor for the 1.3V regulator...
