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 am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
Hej Nordicsemi,
We're developing a new product based on Bluetooth LE. And we would like to know if thousands of BLE devices can coexist in the same area. Preferable all...
No matter what sleep mode I put my nRF51822 in (system on, idle, system-off), it seems that the base current is above 1 mA. Is this how it's supposed to be?
I am using nRF 51422 SDK and SoftDevice v1.0.
I succeed in building and loading blinky example from SDK v12.1.
And I succeed in building and loading ble_app_beacon example...
With this Main.c, I'm only seeing the 1st 4 bytes of the device name in the NRF Connect app.
Note the use of:
init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
Am I using...
Hello everyone, I added NUS library and I change the sdk_config.h file according to ble_app_uart example. When I built my project, I do not get any errors. But the device...
Hi support team,
In order to make the application hex valid after programming in a bootloader enabled project, we can use bootloader-settings.
As for secure DFU, it...
We are upgrading some products to SDK 14.2 and creating some new ones.
We need to start production programming of boards. I can't find the information on how to do this...
What is the maximum and minimum frequency of the PWM signal/square wave that can be measured on the NRF 52DK board I'm using NRF 52832.
Also, what is the max and min "pulse...
Hello,
I have found similar questions on transmitting multiple bytes over SPI, but I am still not sure how to do it. I want to communicate with a driver which needs to be...
Hi,
I found the 'Solar Sensor Beacon' example from
https://github.com/NordicPlayground/solar_sensor_beacon .
There, I found that no softdevice initialisation (nrf_sdh_ble_enable...
I am working through the nordic sdk 8.1 peripheral heart rate monitor example. I am wondering what RR is? I can't figure out what it stands for or what the purpose of it is...
Hi,
In my current project I have indicating LEDs connected via TWI bus. In this case, I can't use BSP_LED_0/BSP_LED_1 outputs to indicate states as it implemented in nrf_ble_dfu...
Hello, I recently use nrf52832 to make a wireless sensor network of BLE concurrently with NRF_ESB.
During development, I use only 2 sensor. Both sensors are connected to...
