I am publishing to group address (group address because in the future I...
Hi, I test the SDK example "temperature", it works OK. I copy the code to my project, there is no compile error, but when the code running on the DK pca10040, the code is...
Hello there,
I'd like to bond between two nrf5 modules and have a real time communication between them.
Now my question is what is the role each would have to play...
The nRF5 SDK is event-driven. So does it mean that the event handler in my application will be directly called in the interrupt service routine? If I write a long event handler...
Hi all,
I'm experiencing a performance drop with BLE proxy enabled in Mesh SDK 2.0.1 compared to Mesh SDK 2.0.1 / Mesh SDK 1.0.1 without proxies (higher packet loss, range...
Hi,
I have project for NRF51822 in IAR(EWARM). Short about project: it based on example BLE to UART communication; it uses SPI, I2C, analog inputs readings, some digital...
I used nRF5_SDK_14.1.0_1dda907.
I opened the bpwr channel then received ant+ packet.
The device received ant+ packet successful.
How do i know that how long time the...

1. I am issuing a gatt characteristic (CHR1) write without the response requested from Central (BLUEPY/BLUEZ, Ubuntu 18)
2. Central than reads CHR2.
Is it possible...
Hello,
If I understand well, when the part of the flash reserved for the PM is full, new bonds cannot be saved until the application deletes older bonding data.
I would...
Hi,
I've heard some stories that that using analog capable pins for digital IO (UART in our case) results in significantly higher power consumption than using a pin that...
I've modified the app_timer library slightly to keep total system uptime, which I can use to keep calendar/epoch time if initialized with the current time from an external...
Hi Everyone,
I examined the document about nRF24LE1 FOTA "nAN18 - nRF24LE1 firmware update over-the-air". The document is about update firm by nrf24lu usb rf adaptor. I...
