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...
Hi Team,
My application is based on nrf51822 SoC in which I am using
BLE and UART interfaces.
There is single UART available and I have used it in communicating with...
Hello,
I am using am using sd_ble_evt_get and sd_app_evt_wait in an endless loop for handling all incoming events.
If I block this loop from executing, I'd expect that...
Hi all
I'm struggling with the easyDMA UART of nrf52. I've got a preview nrf52-DK here where I wanted to make a simple example with the following code but I never reach...
I'm doing a custom board with a nRF51822 FAAG0. I have in it the ST BAL-NRF01D3, with a 0.8pF capacitor.
In the forum I read in a post that some versions of the nRF51822...
Hi everyone,
I am using the nRF51 SDK 10.0.
The documentation for the Debug Logger API suggests sample code like:
uint32_t retval; // Initialize module
retval = app_trace_init...
I want to use the J-link to program the nRF51822 via SWDIO and SWDCLK, every time I click the
"nrf51 programming", the studio stops working immediately, PLZ help, thans
I'm trying to set up communication between an nrf51422, and an nrf24l01+.
The nrf51 is supposed to be the PTX device, and the nrf24 the PRX device.
Communication from PRX...
I was learning GPIOTE using the example provided in SDK 9.0.0. (examples\peripheral\gpiote). The example only uses GPIOTE task and a timer to drive the task through PPI. ...
We have created a firmware and encrypted it with a private key and made it public. When we download it to the chip it's decrypted with a public key stored in the chip. Right...
I have about 200-300 sensors, each requiring to send data at around 0.5-1Kbps to a central node (coordinator/master node), what will be the network configuration/topology...
In SDK 8 for the nrf51422, notifications are always being sent as 20 bytes, regardless of p_len. The BLE_EVT_TX_COMPLETE event stores the proper number in tx_length, but the...
Hi everybody.
I am making an application which combine ANCS and UART on PC100028 (nrf51 SDK 9.0.0). This program worked properly. However when I add DFU service (dfu_dual_bank...
I am currently using Nordic's UART code and wish to build to use the UARTE rather than the legacy UART. I am currently using the following definitions in nrf_drv_config.h...
