Our application is based on nRF5 SDK 17.0.2, 52832, and buttonless secure DFU without bonds. It works fine with the windows nrfconnect app but when testing various phones...
Dear Mesh Experts, Allow me to briefly explain the project:
The firmware contains a generic level server model and the code from the mesh DFU example. It is running on...
Hi,
I want to run a mesh application. Can you please tell me how to compile it using iar ide.
I tried it using segger ide. But I want to try it using iar ide. Can you...
Hi,
We base on the light switch example to include the dfu process into it.
Device FW information is as follows:
Mesh sdk: v4.2.0 SoftDevice: s113_nrf52_7.0.1_softdevice...
Hello, everybody,
I use FDS to write some custom data, when SOFTDEVICE is PRESENT, and i disable the SOFTDEVICE, May I ask if I can still write custom data with FDS?
Hi there!
We are using nRF52840DK development kit with nRF-Connect SDK to build a pre-production version of our product. We have added the required BLE service and characteristics...
Hello, I implemented a firmware based on the multilink central example, with a custom service. I am using NRF52832 (custom board) with SDK v15.2 and Softdevice S132 v6.1.0...
Hi everyone,
I am using the nRF52840 DK and I am experimenting with the USB MSC example. My purpose is to record data from an IMU device and store them in files. Then to...
Hi,
This is a followup from another issue ( link ) which helped with.
The suggestion to modify nrf_serial.c fixed the previous problem, and you can see that the TE (transmit...
I have an expansion board by ST mounting an analog mic (MP23ABS1). The mic out pin (via a diff. amplifier) is given on a connector. I take that signal and feed it to the AIN5...
I'm trying to ensure my firmware goes into power off when it should, and that current consumption is as expected when in power off. However, using PPK2 to measure current...
Hi,
I'd like to use SPI and I2C simultaneously on nRF52832. But I came across this post which says "if you use SPI0, TWI0 is not available". Does this prevent me from...
I took the I2S example from SDK15 and while compiling I am getting the following errors. I tried but I am not able to solve it. The same happen when I have taken twi example...
