before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
I'm looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
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 want to connect a rotary encoder.
So I have 2 pins of the nrf51822 connected to the encoder and I have to check which one change first to increase or decrease the...
So there seems to be a conflict between the TWI and the Softdevice. My I2C communication works over TWI fine in isolation but when i try to send data over ble the TWI doesnt...
I am using the nRF24le1 in Enhanced Shockburst mode.
The datasheet describes how it is possible to upload acknowledge packets, W_ACK_PAYLOAD, to the TX FIFO. And then the...
Hello,
I need to get RSSI with the NRF51422 (pca10031, S110), but i don't want to connect with a central device (i.e. Smart Phone). The central device should scan for bluetooth...
We tried to pair with and connect to nRF51822 DK running HTM app with SONY VAIO fit15e NB and always fail as we did the following steps.
We also tried some devices like ASUS...
Hi,
I just replaced the BLE chip in my board from CC2540 to nRF51822. I simply want to know how to configure the interrupt on a pin as well as rising/falling edge interrupts...
What are the allowed channel numbers for gazell?
In the gazell user manual it states, a possible 80 channels.
While the nrf_gzll_set_channel_table () API reference says...
Hi,
Is it possible for me to completely copy the antenna design from PCA10028 unto my custom board? I don't need a very long range, but I need to make a design fairly quickly...
For PCA10001 have 16MHz crystal, and I use the NOP to test the cycle. And found the device work in 16MHz. How to set this board as 32MHz?
This is my current setting in...
We need to sample all 8 ADC channels for random 1ms pulses to record amplitude data from in real time. How much will that impact the bluetooth performance if it needs to freeze...
Dear community,
I would like to know how to send as much data as possilbe from a Nexus 4 to an NRF51822 based device. For that I think I need to send multiple packets per...
Based on the announcement for upcoming training ( www.nordicsemi.com/.../Bluetooth-Innovation-Trainings) it sounds like Nordic will support the Bluetooth SIG's Bluetooth Developer...
