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...
we update nRF6310...
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...
NRF52,S132 soft device,
I am trying to toggle GPIO 10 (NFC pins Enabled as GPIO)in a 1us Timer, But its not happening , What may be the issue? Am using Timer 4. What is the...
I have programmed nrf51-dk with an example code available at mbed platform,everything works fine except that the ble is visible even if we open bluetooth menu.It is scanned...
Hi,
I'm developing something with NFC / BLE handover - it is currently working fine, NFC tag is read by a phone, nrf52 starts advertising and phone then connects to it over...
Hello,
I'm remaking an nrf52 project in Keil and ran into an issue when it came to compiling. All of the errors outputted have came from bsp.c, mostly stating that a few...
Hi,
We will use nRF52 along with small 8bit micro and UART connection. The MCU cannot support standard baudrate 115200, and we will need to implement non-standard speed...
I am using the Johanson balun ( www.johansontechnology.com/.../Johanson_nRF8001_App_Note_v2.pdf) to interface the differential input of the nRF8001. The PCB manufacture I...
Hello,
I am using the following function call to set up PWM:
app_pwm_config_t pwm1_cfg = APP_PWM_DEFAULT_CONFIG_2CH(5000L, BSP_LED_0, BSP_LED_1);
However, the compiler...
Hello,
I designed a board with a nrf51822 on it. My problem now is, that this chip needs far too much current (with no firmware on it) when I apply the 3V3 power to it. I...
I have been working on a project that involves two nrf51 dev boards, one is acting as a central and the other is acting as a peripheral, and I have been encountering a problem...
Hello!
For beginning with nRF51 I chose BLE Nano set of boards (BLE Nano + MK20 USB donbgle) and it was of great help to easily begin with BLE.
So far, we came to the need...
As an experiment, we want to implement soft power off for nRF52 with external components. We want to keep the entire circuitry entirely switched off, and after a press of...
I do not use board.h nor bsp* in my project, and also I am not initializing the pins that I do not use in my program currently - so P0.17 is not initialized and setup. However...
