How do I receive multiple signals simultaneously at a single receiver (433MHz) with multiple transmitters ?
I am working on a polling system. This one is similar to the audience...
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...
After trials and tribulations I have finally gotten a pulse ox device to work as I needed to. I started with the health thermometer example in the 12.3.0 SDK which is the...
Hi
I tried following the eclipse installation tutorial: devzone.nordicsemi.com/.../
And after a while I got eclipse to handle the Nordic stuff, but when I try to import...
Please find attached several fixes for bugs / incomplete protocol implementation in the MQTTSN stack that we have identified for inclusion in future versions of the SDK. ...
The Thread SDK is pretty awesome! :) However, It does has a bit of a learning curve for me because it only uses UDP instead of TCP.
While searching I found an MQTT variant...
We're developing on a custom NRF53 board. With the I2C bus disconnected from all peripherals, but with external 10k pullups connected, we get the following waveform when attempring...
Hello,
We are working on a research project in Sheridan College to create an indoor positioning system using BLE 5.1’s Angle of Arrival feature. We noticed that nRF52833...
Hi,
I am using the nrf52840dk trying to connect my bike power meter over ANT+, to then forward data to cloud (will be using the nrf9160dk and then the thingy91 once I get...
Dear Support,
I'm evaluating a tiny BLE chip that we can do:
reading multiple three SPI sensors: pressure sensor, accelerometer, and FRAM.
So with your BLE chip...
Hi,
Using 52833 it seems that sometimes the radio quits responding, ie, it is in NRF_RADIO_STATE_DISABLED state and there is
no obvious way to get it out of that state...
Hello,
I'm trying to program the ble_app_uart example program from SDK 17.0.2 in Segger Embedded Studio using softdevice 132 to a custom PCB (with the nRF52832 chip) using...
Hi,
I am using nrf9160 to handle the MQTT protocol and collect the data packets from another microcontroller using the UART interface.
Sending the data to the server using...
Hello all,
since Tuesday I'm trying to get the example project ble_app_uart_c (SDK Version 12) running. Meanwhile I can compile the project without errors, but when I flash...
I am trying to set up the nRF52840DK to interrupt on the comparator input on A0 going above the threshold. I figured, I think, how to set the comparator up but I am havin...
Hello Nordic Wizards,
We are in the final throws of a project preparing to go to market. However we have identified a "strange" problem.
