Apparently there is some limitation on length of the paths with Keil. The paths are specified under "Options for Target" --> C/C++ --> "Include Paths". Due to this limitation paths look like this:
Each folder with header ... (more)
I'm having a strange behaviour when using the TWI HW peripheral for reading from an I2C device. My application tries to read one byte from a register in a I2C device. As background:
-I2C address: 0x55 -Register address ... (more)
I'm done with the hardware interface of my current project. Right now I have a service running with a custom UUID, by writting this characterisitics you have access to the hardware on the device. I am not an ... (more)
i have a service with more characteristics and more states. Not every characteristic should be available in each state. Thus there are services which are just allowed in one specific state.
If a device wants to write the ... (more)
Hi, i need to save an array of 50 kB on the nrf51822 flash. I only need to read the data stored in the array. I come from the PIC micro world where i simply need to initialize the array ... (more)
I've written a nRF51 SWD-JTAG programmer.
I want to enable it to check for minimum softdevice version and error out if a too-old softdevice is found.
It is easy enough to read the softdevice version information from UICRs ... (more)
Hello to all,
Since a couple of weeks I have a problem in a program which consist of three parts:
1.- a Timer to make a pulse train by interrupts 2.- a program to control a LCD display 3.- a ... (more)
I want to communicate four same devices with different hosts. i know that one host can communicate to seven devices and also a device is able to speak different hosts . i want that different hosts communicate with the same four ... (more)
Thanks for the response. As a test, I loaded the same code onto a PCA10004 and it seems to work as you described. A breakpoint at 217 does get triggered when it receives data. So, I guess there is something ... (more)
I have been perusing the source to micro-esb, and it appears that it wants exclusive access to the NRF_RADIO interrupt(RADIO_IRQHandler) and things are designed so that only one can operate at a time. Is that correct?
Is there available device manager for S130 or just i should wait for final release? Or is it possible to implement from S120 example?
I am working with nRF51 to make two BLE device, One act as cetral and another as peripheral.
I have implemented almost functions that the two devices are required. bonding procedure and exchanging data work well.
Now, I ... (more)
Do all NRF51822-DK (development kit) have the same silicon build revision? If not, which distributor should I approach for the latest revision and is there a specific product code that I can use while ordering the latest revision?
I have encountered a problem with the IAR linker where I run into a 32k code-limitaion, even though I have a licence with no limitations. According to IAR, the problem may be that the library gzll_iar.a is compiled in ... (more)
I've tried linking the ESB library in IAR but I am still getting error. When link arm_lib.lib getting this error: Fatal Error[Li014]: error when reading "nrf_esb.o(esb_arm.lib)": Not an ELF file but when link ... (more)
I downloaded the nrfgo Sdk for the nrf24lu and nrf24le. In the projects folder there are several examples, two of which are of interest. The first is entitled "bootloader_32K" and the second is "nr24flu1 gamepad". The problem is that the ... (more)
Hi, I'm having the purpose to use nRF51422 /ANT to connect a relatively data hungry ANT device. The nRf51422 specs expose three programmatically available data rates : 250 kbps, 1Mbps, 2 Mbps. I'm unable to find more details in ... (more)
Can the master control panel automatically confirm indication from peer device?
Hi, I think getting started with the Nordic chips is not as easy as some others. I would like to know what are the first things that I need to run my code on a Nordic? Especially NRF9E5.
What is ... (more)
I am trying to modify the bootloader example provided by nordic. I am able to compile/link my code and use nRFgo studio to run it, but for some reason I can not debug my application in Keil. It ... (more)
Before I call sd_power_system_off(), I do the following:
NRF_TWI0->ENABLE = 0; NRF_TWI1->ENABLE = 0; NRF_ADC->ENABLE = 0; NRF_SPI0->ENABLE = 0; NRF_UART0->ENABLE = 0;
How do I disable the GPIOTE module? There is no "ENABLE" or "POWER" field.
I using nRF51822 ble_app_uart project with softdevice 7.0.
I need to manage my internal flash memory map so i cannot use pstorage libarytest main.txt.
So i try to use flash_page_erase(addr) and received hardfault error
What is the typical range of operation that can be achieved by nRF51822 Bluetooth Smart Beacon Kit ? I know it depends on the Tx power, but can a range of approx 30ms be achieved using the beacon kit ?
I need help choosing between 2 technologies above, my goal is to enable multiple (up to 20) devices exchange small amount of information (around 30 bytes) between each other, then, based on the received information, each device will act (by ... (more)
How many packets can the nRF8001 send in a single connection event? I have seen here, that it is possible to send up to 6 packets with the nRF51822 + Softdevice S110. But there was no mention of the nRF8001 ... (more)
Is it possible to count pulses with the 51822 from an external device in the range of 250-15.000 pulses pr. second, while the CPU is powered down (softdevice sleep)?
I've had a look at the pwm_analyzer sample, which ... (more)
Hi, we've been using nRF51822 for developing application and iOS 7.x detect then just fine. Since I upgraded to iOS 8. Beacons are 'invisible' to our application. I was wondering is somebody else is experiencing the same problem ... (more)
I am using Nordics sample bootloader and I really want to make sure that given a freak accident in sending it the firmware or in the firmware code itself that the bootloader is never erased or overwritten. In its current ... (more)
We want to develop our BLE related application on PC and we find that "GAP/GATT driver for windows" is a good way to achieve that. While our system is based on Linux (Ubuntu 12.04) and currently the ... (more)
