why use 50ms and 400ms connection interval for testing the maximum data throughput(2M,247byte payload)?
Because 50ms can only send a pdu , and 400ms can send up to 8 pdu...
Hi,

Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hi everyone,
I have one problem with the application timer. When I change the state of characteristic to the value of 1, the following code is executed:
err_code = app_timer_stop...
Just stumbled upon a few questions, which are hard for me to answer at the moment.
I wanted to do some throughput measurements with the example taken from SDK 14.2.0 mentioned...
What does the QSPI controller inside the nRF52840 do when the ACTIVATE task is started?
Does the ACTIVATE task result in communications with the external QSPI part such...
Hi,
I have a question about the UARTE peripheral.
is it possible to keep the DMA running and let it write to ram in a circular way?
I used DMA on the stm32 before and...
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...
