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...
The only way I can see to do it is by two separate PPI calls. So Timer1 "tasker" is firing both the capture and clear... but will they execute sequentially?
Hi,
I just bought the NRF52850 DK. Currently I do not have the JLink connector to perform debugging using UART.
Is there is a way I can print printf or NRF LOG through...
Hello expert,
I would like to design a custom PCB that has two transceivers on it. One transceiver is working as a beacon/continuous wave generator (TX) and the other one...
On the basis of NRF24L01 +, an antenna was designed. after designing, I need to carry out the coordination of circuits. Do not tell me how best to do this, what values to...
I had a setup where I could DFU OTA a NRF52832 based board
I moved to a NRF52840 based board and now during the OTA DFU I get messages like this
I did try a new bootloader...
Hello, guys.
We have nRF9160DK and nRF Connect SDK v1.3.0. The version of the LTE modem firmware is the latest (v.1.2.0).
In our design, we are able to initially connect...
Hi Nordic team,
I just purchased a row of new nrf9160 SiPs for our IoT products. We are testing with new made cuicuits.
We use the same circuit schematic that worked with...
Hello,
Problem: BLE doesn't work on a OurBoard with nRF52840 (Schema1).
1) BLE example is working DevBoard (can see BLE server by scanner). On the OurBoard the examle...
Hello,
I've been testing HCI_UART from Zephyr RTOS on nRF52840DK and own device which has nRF52840 + FT232R as USB-UART converter. Regarding the own device it's a circuit...
I am studying the beacon example provided in the SDK (The project is found in following directory C:\Nordic_semi\nRF5SDK160098a08e2\examples\ble_peripheral\ble_app_beacon...
Hello there, I'm developing a device who will use two NRF52832(ANNA-B112 Module). They will communicate as central and peripheral. But i'm facing a problem, i need to after...
I could decrease current consumption at v1.2.0, but couldn't at 1.3.0. 520uA flows in k_cpu_idle();
How can you do that?
Also, in v1.3.0, CONFIG_UART_0_NRF_UARTE is depricated...
Hello
Good day!
Problem: We have got a new nrf52DK, and in our application development we use GPIO interrupts (we have set up 4 gpio interrupts). Surprisingly the GPIO...
