Hello, I have established the connection between two pca10001 boards, one as central and one as peripheral using multilink_central and multilink_peripheral. I have serial...
Hi,my friend,
Now,I use nrf905.Situation is as follows:
I use the NRF PCB circuit of data manual.Nrf905 work, often loss of data.
1.The Product host is to use the stick...
Hi,
I want to use the Blend Micro with more security. I want use a passkey for the Bluetooth connection. For example through the iOS Device.
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...
Hi there,
I'm a beginner with NFC and there is somethings I don't understand with the NDEF Messages frames. I have a the PCA10040 Development Kit.
I've seen this schematic...
Hi All!
I would like to implement the DTM nterface over USB VCOM instead of 2xUART (from examples).
Is it possible co-work USB driver (VCOM) and DTM from samples together...
Hi All,
I use 2 peripheral and 6 Central roles coexisting.
Not clear the order of conn_handle number assigned by SD during BLE Connection.
For example.
After Central...
I am new to nRF programming. My "far away goal" is to make a BLE sensor mesh with a centralised data collection.
Currently I am deciding what libraries to start playing...
Peripheral device has 2 services,but central can find only 1 service(0x1001).
I want to find other service(0x0001)
According to the message seems to be looking for 0x1001...
Hi,
I'm using the nRF51 dongle with nRF SDK 12.3.0 and the S130 2.0.1 SoftDevice to implement a BLE central. The dongle repeatedly connects to a BLE peripheral, performs...
I'm running the PB Remote Client on a PCA10040.
I have 2 servers running on PCA10040 boards.
Watching the log whilst debugging the client, I receive the following: ...
Hello all,
I am new to nRF platfrom, I am working on a protect which contains multiple BMD-200 modules with nRF51822 controller. It has to transfer some data via UART,...
Per this blog, I understand that the nRF52's ANT pin must be matched to 50ohm via L1/C3 and that the antenna must be matched to 50ohm. Hence a trace with 50ohm characteristic...
Hello, the title is pretty descriptive.
I've tried to read through previous questions and got a rough idea but decided that it would cost too much time for me to explore...
I am working on a ble application using an nRF51822 that requires low power consumption. I'm curious if on average the observer or the central role will consume less power...
We have our own custom board using nRF52832 (via Laird BL652 module). Until recently, we have been programming our application, bootloader and softdevice using the PCA10040...
