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...
Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
Following the instructions from the bluetooth sniffer guide, the sniffer code finds my device. I then attempt to launch wireshark (which has been installed) and I get a plugins...
I'm trying to download a HEX file to an nRF51822 using Keil and ULINK PRO. The hex file was generated by the mbed compiler and works if I drag and drop it using the programmer...
Hello devzone...
My setup: nRF51422 and S110 peripheral
My setup transmits IR data on reception of Bluetooth data from a central device. I have used PWM for generating IR...
I bought 5 Seeed Micro Ble Modules. On their Website they answered a question 7months ago, that they ship with QFAA G0. I connected them via SWD with my nRF51-DK.
God damn...
I am trying to decrypt some data.
My data is encrypted using AES-ECB No padding method.
I know the 32Byte key used for decryption.
Following is the code snippet. I am not...
I guess and hope not but I am a little confused by the compatibility matrix..
I would need to use SDK 7 or higher for my nRF51-DK
but I would need to use SDK6.1 or lower...
Hi,
I searched here for a while and I couldn't find the answer. I implemented custom service by referencing nAN-36 and the github code. For some reasons, the github code...
Hi there,
I am trying to generate a pulse on a pin using RTC1 and PPI. Using a TIMER this works fine but my goal is to incur minimum current consumption by using only the...
I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
In the sensor datasheet it says one can use SPI_Mode 0 or 3 (doesn't say that there is anything to do to switch between them).
I connected MISO from the DK with SDO from...
I want my application to cooperate with DFU. I am using example DFU project from SDK (6.1) (from nrf6310 folder, i simplified it so it could work on PCA10000), but i need...
I increased my IRAM1 size as advised here , but now my program doesn't work anymore on the nRF51 DK.
I know the problem is somewhere in the memory allocation, because when...
I am working with nrf51422 chips version 2, so according to this table taken from the compatibility matrix v2.0, the last supported versions of SDK/SD/SDS I should refer to...
Also it seems not to advertise. What may cause this problem?
All I could found in the ble_gap.h is:
If both conn_sup_timeout and
max_conn_interval are specified...
Hi
I am trying to debug the "ble_app_hrs" example from SDK 6.1.0 (using keil IDE), on 51822 chip.
The IROM1 is defined to start at 0x16000 (meant to be used with softdevice...
