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...
Hi, Nordic Engineer:
Would you like to give me some advice? On my hand, i have a slave ble device(not nrf51822, also i can not change the code). I want to run s120 softdevice...
i am able get the status of led of pca10001 board using usb dongle. now i have to make other pca10001 board as central and want the same data of it? Kindly help, i shall b...
We are planning to optimize the radio-frequency signal,so the some docunments like Simulation model are needed.which can help optimize the RF signal through ADS simulation...
In ble_advertising.c, line 165, you can see such interesting code. I assume it is a copy/paste error:
if(p_advdata->p_tx_power_level != NULL)
{
m_advdata.p_tx_power_level...
For the first, impressed by your intoducing NRF52 chip.
Question: what`s NRF52 indoor range using onboard antenna and maximum output power (+4dBm)?
Thanks.
Hi~
I am struggling to get the BLE packets detected by nrf sniffer (v1.0.1) using wire shark. Its only showing "ADV_IND[Malformed Packet]" periodically. I didn't understand...
I believe what I am asking is extremely specific, but keeping hope that I might get some direction
I have used a clone ST- Link v2 programmer to download code into a NRF51822...
Hi all,
I would like to trigger some actions on difference devices communicating with the ANT protocol based on the distance they are from each other. A simple example...
Hi
The documentation for the new feature in S110 v8 to change the gatt table size says that to change it the linker configuration needs changing .
This means it is a...
Hi all,
First of all thanks for Nordic team for the excellent support. It is very useful for a beginner like me to get started on BLE development.
I am using the nRF51422...
The issue is that if a peripheral needs to enable interrupts (or anything else partly protected by the SoftDevice) and is configured before enabling the SoftDevice, the NVIC_...
Hi, I use nRF24LE1 configured for power down on register retention mode with RFRx active.
When the CPU is on power down i don't have any interrupt from RFIRQ.
