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...
In the Keil debug interface, how can I find if the application is throwing an ASSERT, and which it is? I'm using the S110 softdevice. (See other question for context devzone...
Hello, I have a weird problem, the nRF24L01+ is sending a TX PAYLOAD that was left in the TX FIFO (clocked with W_TX_PAYLOAD) as an ACK PAYLOAD when switching to PRX mode...
hello everyone,
i am trying to use SDA and SCL pins of TWI other than 24 and 25, is it possible? i want to know before using other pins for twi other than 24 nd 25 with...
Hi
I try to communicate with others TWi devices using the twi_hw_master driver.
When i initiate a communication with twi_master_transfer , i don't receive any ack from...
Hi,
I have purchased the nRF8001 Development Kit and so far I wired the nRF2740 board to a FTDI VNC2 microcontroller. I have been reading about how to configure the 8001...
Hello. I'm trying to port the ble_hrs to a custom board with an NRF51822 on it, but the advertising never starts. While I'm debugging this, what should I be looking out for...
Is there an example for sleeping? I just want to put this thing to sleep drawing minimum current and have it wake up on a RTC timeout, but do not seem to be able to achieve...
As indicated in the PS, System On Mode idle draws only 2.6 uA.
Does this mean that if I install and active a timer interrupt, where the interrupt routine places the system...
Hi,
I am new to ARM development. We are thinking of ordering mkit for evaluating and developing a custom BLE service(profile) which sends data to BLE client (probably a...
Hello Everybody!
I have been working with BLE security and I have an issue with OOB setup.
I'm setting my nRF with the following:
m_sec_params.timeout = 30;
