Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi

Hi Team,
Is it possible to scan on one channel and advertise on another channel?
Say node-A will scan on ch-37 and advertise on ch-38 while
node-B will scan on ch-38...
I'm trying to use the NRF51DK to talk to this EEPROM ( www.st.com/.../CD00290537.pdf) . I've started by trying to modify the twi sensor example. One of the things that's different...
I am new to nRF51:
how do I change the softdevice from 110 to 130 in the example project ble_app_uart (and in general) within the Keil µVision IDE.
There is no option...
Hi,
I am developing a product for the 433MHz band. Due to the space constraints I had cut the ground plane to very small and also had to rearrange the components away from...

Hi,
we are using RTC2 with APP_IRQ_PRIORITY_LOWEST. But the code hanged inside the interrupt handler. when we did step through debug, we came to know that in nrf_drv_common...
In nrf52_SDK/examples/peripherals/rtc we tried adding the UART prints and verified. It was working fine for RTC0 but fails to do for RTC1. Could you please give any hint on...
Hello together..
i have a problem with the nRF51 DK.
I tried a little bit with this DEVkit i.e. copy the blinky example to the JLINK storage.
This works fine.
Regarding...
Hello,
I am developing a new product using S130 on nRF51822(QFAC). My product use LCD as spi interface and ADXL345 sensor as i2c interface, also test it, works well without...

I am trying to set up a GPIO interrupt, and found that whenever Button 1 is pressed, if Button 1 or 2 is pressed later, the app will reset. This is even if there is any other...
Hi.
I want to make a device which can connect each others and communicate with NUS.
I need not to use any other service without NUS.
I made nus_c service which is a central...
Hi
I can't seem to find this in the datasheets, what is the active current consumption of the nRF52832 chip, I'm interested in the maximum expected current consumption...
Hi!
I want to connect a nrf51 dk with a beacon and I'm using the UUID to make the connection. In the beacon code I define the UUID in this way:
