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...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
I control a module over UART using app_uart_fifo. This module is controlled from nRF host by commands to perform things. This generally works fine but however, sometimes when...
Hi,
I write a code for the max6657 temperture via modifying the SPI MASTER Example. The function for reading max6675 via SPI is shown as follow
uint16_t readCelsius(void...
Dear Nordic Team,
Thanks for supporting.
How to calculate the battery voltage level from Eddystone TLM. Its always transmit 240mV.
I am using CR2302 3V battery.

Hi all !
Can you tell me if it is possible to flash a single nrf51822 ship directly or if it requires at least the minimum oscillator X1 in order to be flashed?
The...
Hello. I want only 1 to 1 bluetooth matching about nrf51822.
I want only 1EA central with 1EA peripheral matching.
I set as below.
1EA - Bluetooth Central - UUID...
Yesterday, I asked a question (so far, no one has answered) about how an OS upgrade on my desktop computer might have broken my ability to flash and run BLE apps on the nRF52...
Hi there,
I have two nRF52 Preview DK boards, SDK 0.9.1 and 0.9.2, and SoftDevice S132 1.0.0-3 alpha. Several months back I got the Bluetooth heart rate demo from SDK 0...
Hi,
i am trying to wake up the nrf52832 from system off with a gpio interrupt.
When the signal on my gpio pin 28 goes from Hi to Lo, i trigger a callback function in...
Hello all,
I'm building a project on the nRF52382 with the S132 (v2.0.0-4.alpha). The project includes a Central device (GATT Clients) that read and write to 2 peripheral...
Are there any specs available regarding the performance of the nRF52 ADC's internal voltage reference? Accuracy (%) and temperature drift (ppm/degC) would be good. I couldn...
Hello,
I'm developing proprietary radio protocol using nRF52 (not using softdevice) and would like to know if it is allowed to write NRF_RADIO->FREQUENCY register while...
Hello, I've got a problem with an app_timer
starting from the BLE_UART example, I've set
#define APP_TIMER_PRESCALER 4
