Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
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...
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...
I am using a nrf51822 based tag and Android official SDK to implement my custom app. I perform the following steps:
1. Scan
2. Connect
3. Discover services
4. Write...
What CRC type is used for the crc calculation with the function
uint16_t crc16_compute (const uint8_t * p_data, uint32_t size, const uint16_t * p_crc )
of the nRf52 SDK...
Hi
I have a prototype of a board that uses a nNF52832 to communicate over Bluetooth, the board has some buttons intended for user input.
As the board size is little...
Hello!
I am sorry to ask a simple question that why my device can't program the ".hex" file about the demo of ble_app_hrs_rscs_relay_s130_pca10028 after I have already program...
Hi,
I have Wifi MCU connected to nr51822.
I download the binary file from a Cloud and need to transfer it via UART, so i need a C code of the nRF5x Programing tool....
Hi,
I am not able to make software breakpoints working with a Segger J-Link probe.
As an exemple, here is my assert callback function:
void __attribute__((noreturn...
Hi.
I'm using nRF51822QFAC, SDK10.0.0, S130.
I want to use DTM code to get SIG certification.
In your example, there is no source code for S130 but S110, S120, S310....
My BLE application needs to occasionally (1-2 times a year) send large amounts (several kbytes) of data, and I'm wondering about how to make this happen as fast as possible...
I am just wondering if anyone else has seen this issue.
I am working on the ble_app_uart_s132_pca10040 on the nRF52 DK.
Using the Android UART v 2.0 app I can connect...
Hi:
A peculiar problem:
I configured an Arduino (atmega328P) to be a receiver and an atmega8A to be a Transmitter Things are fine. The Arduino receives a 10 byte string...
We are developing a beacon device with 10dBm power amplifier. During software development we noticed the control signals provided by ble_common_opt_pa_lna_t align poorly with...
Hi,
As title ,
I try to add the NUS service that show on the ble_app_uart project into Multi-link project.
But it doesn't work .
I want to a central connected to at...
I want to use PWM on only one output pin. I'm using a nrf51422 and softdevice s130.
I want to be able to set the PWM and then change it again (a sequence). This is to be...
I have tried using the pre-built nRFUart Example in the Master Emulator API (2.1.11.1) and get the above error
I also tried rebuilding - no change.
I do have a PCA10000...
