Hello,
i'm working with my own board with the SD V6.0 and nrf51822 chip id QFAAG0. Already works fine.
Now i switch to the new SD V8.0. The SD V8.0 is programming with...
Hi everyone,
I'm working on the nrf51822 chip and using S110 stack of SDK 6.1. Everything is fine for IPhone5s. The proximity example is running on the nrf51822 device...
I have used your example of a bootloader nAN_18. I can create a basic program, with new firmware, and also load my new bootloader program at the high end of memory.

Sorry if these questions are discussed already. I'm a newbie to Bluetooth project. Let me explain in brief. I have a central and peripheral device. I am transmitting 10samples...
After quite a few difficulties getting Keilv5 to work with the included examples with no responses ( devzone.nordicsemi.com/.../) I decided to give Eclipse a shot.
This...
Good day All,
We are in the process off procuring a project using nRF52, and I need to find out some important things. Are there any costs in using any of the libraries...
I am using nrf52840 module(peripheral) for transmitting 10samples/10ms and central device as the same nrf52840 for receiving the samples. Although I receive the packets, there...
Hello,

Hi,
i'm wondering if there is any IC (for example nRF52832) that can reach a range up to 155 meters available within the Nordic semiconductor catalog ?
i know that the...
In nRF5 SDK 12.1.0 a bug was fixed in nrf_drv_wdt_init(). Watchdog timeout could not be larger than 131 seconds because of (x * 32768) multiplication before. This bug is again...
In the spec it says that the typical ramp up time is 140us (or 40us in fast mode). But there is no details on maximum or minimum. What is the true tolerance on this value...
We are building a simple project, let 51822 connect the mobile, once per second. We found that the Tx power of 51822 is getting weaker and weaker (view the voltage over a...
I have a nrf51 dongle and would like to use PWM on 3 pins.
Managed to get it working on pins 15 and 16, but somehow pins from 17 to 20 just don't work.
For example: I set...
Hi,
I have two nrf52840 boards and I am using the ble_app_att_mtu_throughput test app. The tests seem to be working OK, but I am not getting the throughput I was expecting...
When performing flash operations, i.e. via FDS or FSTORAGE, etc. - will GPIOTE events be captured and 'queued' until the CPU is no longer halted?
Said another way:
