Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"
to develop a new project, and encounter some questions...

Hello,
How many RX buffers are in S110 SoftDevice? I know there are 6 TX buffers (so you can send 6 packets per Connection Interval).
How is it on receiving?
Is it e...
My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
My android Proximity application fails on service discovery only for the very first time it connects with the devices(nrf51822 evaluation kit with sdk 5.2.0). Actually...
Has anyone converted the app note AN34 DTM Python script to C# or C/C++ ?
The Python DTM script is works OK with the setup specified in the app note AN34 figure 2, which...
I'm looking to maximize the throughput using Gazelle on the nRF51.
Assuming zero retransmissions, I believe the theoretical max should be (1/TimeslotPeriod)*PayloadSize...
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...
