I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
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...
Hi all,
I am new to nrf51-dk and I am using nRF5 SDK v11.0.0.
I wanted to perform the task below.
When the DK is turned ON, read on board push button status.
If button...
We are implementing scan functionality in nRF51. I would like to understand if anyone has tested or tried to scale this functionality when there are thousands of beacons around...
Hi everyone,
I was wondering how GAP calls and events are synchronized within the SoftDevice.
Example:
// conn_handle is updated in the CONNECTED and DISCONNECTED...
The Android Master Control Panel app has an option to remove bond information (which works). But the API for it is hidden .
I'm just wondering if you use reflection to...
