Is it possible? Static passkey...
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...
There is some doubt about the nRF2401L+ RF matching circuit.From the article of <<Tuning_the_nFR24xx_matching_network.pdf>> ,it says "The balun-function is done by the 180...
Is it possible for a nrf51822 running s130 to advertise and scan at the same time?
I am trying to scan for other BLE devices using s130 softdevice, but cannot find an example...
Hi,
I have learned that you can change the MAC address on a device by using sd_ble_gap_address_set. However, when I press the sw2 button on the beacon (running a modified...
While reading about setting up nRF51 development environment on OS X , I came across the following:
Unfortunately the only way to erase
the memory is to do some magic...
Hello everyone,
I am trying to communicate among 2 NRF24L01+ modules using 2 ATmega16A microcontrollers.
My SPI communication is working fine as I am able to write and...
I've tried to set up my own BLE project as an exercise in understanding what's going on. It's going okay, with the exception that the device isn't advertising the data that...
I write PWR_UP using SPI and then read the Reg <0>. but I am not getting what I wrote.
Step 1 : Power ON using 3V.
Step 2 : Delay for 1 Sec to get into POWER DOWN MODE...
Hello,
On my custom board, I'm receiving chunks of UART data, without flow control, at 115200bps. Sometimes (its quite frequent now... sometimes after 10 chunks, sometimes...
I'm working on a PC application (using nrf51-ble-driver_win_0.4.1 API) to connect a BLE device and discover BLE services.
Today, I'm tying to connect the Nordic dev kit...
When discovering services using nrf51-ble-driver_win_0.4.1 driver, some ID are received with type BLE_UUID_TYPE_UNKNOWN. So I assume they are 128bits. I then retrieve the...
I downloaded the BLE beacon app S110 v7.1.0 to a nRF51-DK board. The current measurement pins were attached to a 10 Ohm resistor.
I observed the AC-coupled voltage at one...
Hi. We've got a chip with a code QFACA10. I am trying to find out if there is the internal pull-down of SWD line or not. It seemed that adding an external pull-down had positive...
