Hi ,Nordics
when I use my host device (reffered to the example of ble_app_hrs_c)to pair and bond with a peripheral device(a gamepad) ,the pairing failed .I don't kown the reason .And when I try to enable the cccd , it failed . I want to know why…
Recently,I confronted some particular circumstance that I have never came across.
The device programmed used by Jlink and Keil,so I check the address of flash,it showed as follows.
Then I readed the code used by NRFgo Studio,
Obviously,this…
Hi, for carrier and modulation carrier signal is confusing.
What is the difference between their center frequency point for same frequency? Or modulated carrier will change center frequency? if it is,why?
What is the difference between…
Hi,
I have my 2 nRF51 running with S130 v2.0.1, one is the central and the other peripheral.
I am transmitting audio data between both and want to reduce the current consumption to the maximum of my ability.
1st case:
My configuration for the…
as far as I am concerned, when I use PPI or SHORTS without interrupts, I DON'T need to clear the corresponding event registers, and task will be triggered once the event is generated. But when I enable interrupt, I have to clear the event register, otherwise…
Now,I use a 1s timer to calculate the clock.
At first,I use the telephone to adjust the time to fit the telephone time.
but finally(after a night ) the result runs fastly compared with the telephone.
For example,the telephone time is 8:40,but the devices…
I am working in the SDK10.0 ble_app_uart_c(master),it can connect to ble_app_hrs(slave) successfully.
But if I add a new 128 bit UUID named ACC_BASE_UUID different from NUS_BASE_UUID.After I power on the master device,it can connect to slave,but the…
I use SDK9.0,SD8.0,the device is 51822AC,the device can enter to Bootloader mode.
As it shows below.
Then I selected the .zip file to start DFU
But when it reached to 99%,the sequence happened.
The system still run the old code.
So I check…
Hi,I have a question.
the PCA10005 board's P0.17(Or other pins) connected to 2.8 v voltage,but the Vcc is not connected,and the PCA10005 GND connect to 2.8V GND.The PCA10005 work(Uart transmit data),and the Vcc is 2.03V.Why ?
Hi Nordic expert, I wanna get a profile of 51822 performance cycle count. I found 51822 has no powerful DWT feature as cm3 or cm4, would you share me some feasible methods to do that? Are there some IDE tools can show this infromation? Thanks.
I am working with the nRF51822 S110 and having trouble implementing SPI. In other devices' SPI protocols, MISO can be held high until the device is ready to transmit data. I want to bring MISO high and then set it low once the SPI_SLAVE_BUFFERS_SET_DONE…
