 Recently, Google introduced some news about Eddystone. At the same time, we released a first implementation of the new specification on GitHub to get developers started. I would like to share some insights on what this is all about.For those of you who are unfamiliar with Eddystone you can find detailed information on these websites: https://github.com/google/eddystone https://developers.google.com/beacons/ What’s new in Eddystone?A new Eddystone GATT Configuration Service enables simp...

We in the Nordic Support team have created an online power profiler to estimate the power consumption during a BLE event with different parameters. The profiler gives you information about the different components in a BLE event as well as the average current over a specified interval. All data is based on actual measurements conducted on the nRF52, and they are correlated with the BLE power profiles found in the SoftDevice specification to build a model which estimates the current components involved....

Why use trace"Embedded Trace Macrocell (ETM) allows to capture information on the processor’s state without affecting the processor’s performance. Microcontrollers that include an ETM allow detailed program execution to be recorded and saved in real time. This information can be used to analyze program flow and execution time, perform profiling and locate software bugs that are otherwise very hard to locate. A typical situation in which code trace is extremely valuable, is to find out how and why...

Hello,Suppose I flash a device that uses the nrf52832 with a serial bootloader, SD and valid application, can I still write to UICR regions via a serial connection using nrfjprog/nrfutil, or must I use a different method to write to UICR? This is to write a unique ID for the device into UICR via a usb connection to uart.For example, will the following lines work without a J-link emulator: nrfjprog --family nRF52 --memrd 0x10001080 nrfjprog --family nRF52 --memwr 0x10001080 --val 0 nrfjprog --family nRF52 ...

Hey guys,I am currently using the nRF24L01+ (more specifically the module that has +pa +lna), and I am experiencing some odd behavior. I will briefly go over the devices, and then will describe what I am seeing.I have multiple PCB's using a Parallax Propeller chip to communicate with the nRF24L01+. For the most part, these devices are working and are getting the data across. I started collecting transmission/receiving/echo data for all of our devices and storing them into a spreadsheet so we can compare t...

I configured my system to sleep after inactivity time. nrf_gpio_cfg_sense_input(WAKE_UP, NRF_GPIO_PIN_NOPULL, NRF_GPIO_PIN_SENSE_HIGH); err_code = sd_power_system_off();when the system wake up from sleep (I use external acceleromter to wake up the system), the RTC1 timer value reset !!!I use the following method the read RTC1 timer uint32_t ticks_per_second; app_timer_cnt_get(&ticks_per_second);how can I prevent the RTC1 timer from reset at sleep...
