I noticed that there are some instructions for testing keyboard on win8.1 or USB dongle. Can I test it on my iPhone5s which is iOS7.0.4 now?
Hi, While testing the device firmware update through the nRFtoolbox android application, i get "device has no required service" error more frequently.
I use latest version of sdk for nrf51822 evaluation board and latest version of apk for Nexus 4 ... (more)
Attempting to program a softdevice hex file using Keil uVision and an ST-Link V2, I get:
No Algorithm found for: 10001000H - 10001013H
This is in the UICR (User Information Configuration Registers), which should be programmable like code according to the ... (more)
Hi, If i am running 2Mb radio channels, how many can i have operating in the 2.4Ghz space concurrently?
ALso, what mechanisms can be employed to detect and move frequency if there is interference on your channel in an ... (more)
I'm confused with the functions (sd_power_mode_set and sd_app_event_wait). 1.I think there are described with the same function.I can't tell the difference between this two.And I can't find the function that is used to ... (more)
There are some include dependencies that go like this:
app_uart.h -> app_util.h -> app_error.h -> nrf_error.h
and nrf_error.h is under Include/s110.
In order to debug some stuff happening with my UART peripherals, I'd like to do ... (more)
Can someone explain the reasons/benefits of using the single vs dual bank BLE boot loader?
Actually, why isn't there a single bank BLE bootloader in the example project in SDK 4.4.2? Is there one added in ... (more)
Hello, i would like to make device which will be dynamically change connection with centrals. It should be connected to the nereast device (with the most power). So I will have several paired centrals. I suppose as perepheral my device ... (more)
I'm having some trouble successfully entering ON,IDLE mode. I have pared-down my application to do the following:
1) Initializes the app_timer using the scheduler:
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS, APP_TIMER_OP_QUEUE_SIZE, true);
2) Initializes the BLE stack and softdevice:
BLE_STACK_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION ... (more)
I am building a new PCB board for a prototype. It will be used for proximity. It will blink on low battery. It also has a piezo speaker attached to a pin as well. My question is this. Can I ... (more)
I want to control GPIO toggle by PPI. Timer1 is in timer mode. CC is 1000, and CC is 8000. I use compare to toggle gpio18 by PPI. I also want to use compare to toggle ... (more)
We have a project for a sauna controllunit, A remotcontrolle and hostunit which controlles the sauna. The Device send comands to the host, the host sends Ack + Payload (the payload includes some informations that the remotconrolle needs to know). We ... (more)
We start to migrate our equipment from nrf14L01 receiver to nrf51422 receiver in order to serve more equipment. I am using nrf51822 to receive propietary protocols from heart beat monitors using normal shock burst protocols (not extended shockburst). I am ... (more)
Hi, We have a custom board with nrf51822 and we use chip antenna from ST BAL-NRF01D3, now the distance it support is very very short (less than 20 cm). So, please tell me, changing the transmission power level will increase ... (more)
I have an application that reads an nRF51822 pin configured as analog input and then sends that value using "ble uart" (included in Nordic's sdk). Analog input is read in an interrupt 250 times per second, but only a ... (more)
Im stuck that i can't get my Motherboards to update. Just goes into an endless loop of saying toggle power to rest it, starting boo loader, Couldn't start.. etc etc..

Hi, Is it possible to control the drive current of the gpio pin? Can anyone explain the different possible drive configuration for gpio's (S0S1,H0S1, etc..)?
I have some questions regarding S110:
1) Is it possible for the S110 softdevice to scan for broadcasts?
2) Is it possible to create a connectable broadcast? I only need to send 2 bytes of data, so can i ... (more)
hi Ole Morten:
thank you for your great support.
i have tested nrf6310\temperature_example. at 30(Celsius)
I checked the data. NRF_TEMP=0x000002AF; TEMP=0xFFFFFFAC; what's the NRF_TEMP data type? 10bit 2's complement or 32bit 2's complement ... (more)
We are using a custom hardware design based on nRF51822. Recently we switched to the new chip version QFAAG0 with softdevice 6.0.0.
