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 uploaded a sample code into an external nrf51822 module using nrf51-dk as explained by this blog www.instructables.com/.../ . power supply for the external module was from...
Hi
The following ticket explains when I configure pin21 as RESET it will be hardware configured to pull-up internally. https://devzone.nordicsemi.com/f/nordic-q-a/8342/nrf52832...
Hi all,s
I have a couple of nrf52840 boards and i was testing the ble mesh light application. The application works fine, but i changed it so it will periodically set...
Hi, I have tested thingy52-mesh-provisioning-demo in NordicPlaygound on github. It works fine by using a precompiled hex file (via nRFgo Studio) but It doesn't work (light...
Hi, I'm working on enumerating the 52840PDK as a CDC ACM device and I'm running into an issue where it's fully enumerating 80% of the time.
After doing some checking I've...
I'm working with TI's TAS2555 DAC as an audio output driven by the NRF52 via I2S. This DAC requires that the I2S clocks (MCK, SCK, and LRCK) are enabled prior to any data...
I understand that the next version of the mesh SDK will have the GATT proxy implemented. Even after reading the mesh profile specification the following is unclear:
- Is...
Hi,
our product is small tag, size of 70x35mm2.
Plastic covers are welded together and now looks like after welding some HW does not work properly. Flashing is successful...
Hello, I am running ble_app_uart_c example on nrf52832 IC. It is connecting to its corresponding peripheral and I achieved bidirectional communication.
The problem is,...
Hi! I am using SDK15 to develop an application for nordic chip which won't be using any kind of display nor keyboard input, so probably I'm gonna go for static passkey option...
I have and older board which is the PCA10028 with the nRF51422 chip.
I have downloaded the nRF5 SKD 15.0.0 and found there is not example DFU project for my particular board...
Hello
I am working on a project based on the Mesh SDK 2.0.1 light_switch example. The system is using SD 6.0.0 and PCA10040 boards. DFU is successfully implemented on the...
Hi,
I work on nrf52832 with the serialization.
The nrf52832 connectivity part is load with S132 V6.0.0 (uart hci).
The stm32 will communicate with the 52832 throught...
Hello, can you say me:
1) which Stack parts in Mesh SDK: nrf5_SDK_for_Mesh_v2.0.1 are implemented in harmony with Bluetooth Mesh Profile Specification and which are not...
Hi,
We are attempting to send data via BLE every 100 ms using an app_timer. The app_timer sets a flag and in the while loop in main.c we call
ret_code_t err_code; do ...
