First time here? Check out the Tour!
I write this code to set my ble device power down,but it causes reboot without any error report.
GPIO_WAKEUP_BUTTON_CONFIG(LEFT_BUTTON_PIN_NO); GPIO_WAKEUP_BUTTON_CONFIG(RIGHT_BUTTON_PIN_NO); err_code = sd_power_system_off();
when I comment out this two lines
//GPIO_WAKEUP_BUTTON_CONFIG(LEFT_BUTTON_PIN_NO); //GPIO_WAKEUP_BUTTON_CONFIG(RIGHT_BUTTON_PIN_NO); err_code = sd_power_system_off();
power down ... (more)
I've a reproducable behavior i'm not able to explain. I'm using the softdevice S110 6.0 on a nRF51822.
The firmware implements some BLE profiles and uses TWI Master with the software TWI master driver from ... (more)
Is there a way to map external memory (SPI connected) to force the app to start execution from there ?
If not feasable , there is a way to transfer the execution from internal flash to an external one and switching off ... (more)
Hello: I am using NRF51822 to design somethings. And I want to use interrupt send method instead of polling send method. NRF51822's UART0 provides TXDRDY interrupt. After serial output one frame, Hardware set TXDRDY to 1, and then program ... (more)
I am developing hid_mouse . When I connect Android once and ubond hid_mouse I must set bluetooth off and on again to connect ble device otherwise it will connect again to the Android auto but can not work normal.

I have a 51422 board design and I just got Ant-FS working with our firmware so I can now download data from an external SPI flash to a desktop application.
I want to be able to update my code on ... (more)
When my application is running on the nRF51822 (e.g. the hrs example from the sdk), I want to stop this application (e.g. at a breakpoint), investigate some memory and than continue the execution. But it looks, that it ... (more)
I am trying to set a value in the NRF_POWER->GPREGRET when softdevice is running, but it doesn't work. I don't get any error, but the value is always 3 and not 1 like I would.
Here ... (more)
Is possible to generate 4 different pwm with the NRF51822 ?
Hi, I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is 4.4.2, and SD is ... (more)
Hi to all, Ihave a problem with erasing flash on nRF51422 Evaluation Kit. When i click on Erase all button in nRFGo Studio everything is looking normal ( segger led is blinking, no errors in nRFGo Studio), and i receive "Erase ... (more)
my application is based on the BLE example: ble_app_hrs. it works well before, but when I add some functions to configure the GPIOTE , and then download to the Device, it doesn't work . And I can't download or debug ... (more)
Greetings, and thank you ahead of time to anyone willing to lend some advice.
I'm implementing application-layer security by requiring central devices to supply a user-configurable password. This is being done in order to maintain compatibility with a security ... (more)
I am having an interesting issue trying to send packets. Only a very small number are being received (~1 per second even when transmitting one after another), and they are only partially correct (receiving 0x9DAFAAAA when transmitting 0xAAAAAAAA).
Additionally, if ... (more)
It has been mentioned in several threads that the MCP/dongle (on laptop) cannot support transmission of more than 1 packet per connection interval. Could you help clarifying whether this limitation is due to MCP implementation or is it ... (more)
Why does this simple float arithmetic cause my GDB client to hang and my GDB server to say "GDB closed TCP/IP connection"? I'm sure I've got other float operations working just fine.
float a, b, c; a ...
I'm trying to just set up a Timer for 8 MHz frequency and have that output on a pin. It seems simple but I'm having some problems (the frequency is a lot lower). What am I doing wrong ... (more)
I have a development dongle PCA10000 , PCA10001 board and nRF pebble.
My aim is to come up with a project where one of these devices
a) would advertise, b) the other device would do active scan, send a scan request ... (more)
I have set up the UART example with PCA10000 and PCA10001. Everything works fine but one strange thing is the time to send 100kB of data. See my times below:
38 seconds 57 seconds 57 seconds 58 seconds
Then ... (more)
I have nRF51822 and after one attempt to use it as a sniffer I have erase the demo app or everything else on it. Since then I was unable to turn back as it as it was. Also ... (more)
I am having trouble in downloading firmware to my development kit. Previously, everything worked and the module already flashed with my BLE firmware. Today, as usual I power up the device and everything works well (detectable and connectable with ... (more)
I wish to inform Nordic about this issue with jlink OB used on EK boards when used in OS X environment.
J-link OB returns " Can not connect to J-Link via USB." and a CDC disabling is due to establish a ... (more)
i took the example in AN36 (with the led but deleted the button stuff) and added the Battery Level service. Both are working fine together. On top of that I took the battery service and coustomized it like shown ... (more)
We survey APPLE's ANCS right now! But we have a question that need your help
We see the sample code experimental\ble_app_ancs There are 1 base uuid and 3 service ID(cp,ns,ds) those need to added ... (more)
I see a master control panel software that can be used to control a PCA10000 USB dongle for BLE applications. Is there such a Sensor simulator application for the same dongle to simulate HRM, Cadence etc sensors? This would ... (more)
I'd like to have a short email dialogue with someone familiar with Arduino programming. Probably not a suitable forum topic; would someone be willing to email me? or.. message me. TIA Tony
This is my first time working on Nordic-made IC.
My previous experience is on PIC which has its own compiler (relatively cheap at 200$). I'm shifting to nRF51822 development kit and I recently read a document about development with ... (more)
I found one from Garmin, but it is for iPhone 4. not the 5's superduper lightening connector :D
Or I have to get an i5 to i4 adapter??:(
I am using soft device S110 ver 6.0.0 with nrf51822. SDK version is 5.1.0. Reading the source of SDK, I see that it must be possible to create multiple hid services. I am having few difficulties ... (more)
When using BLE_GATTS_VLOC_USER with a variable-length characteristic, we still need to use sd_ble_gatts_value_set to keep SoftDevice appraised of updates to characteristic value length (and presumably other bookkeeping).
A major motivation for using VLOC_USER (for us, at least) is for large ... (more)
