Hi,
I am trying to implement protobuf for my application. I have seen that nano-pb library is there in SDK file. I want to use it in BLE-UART communication. How to do with...
Hello,
I am using RFX2411N RF amplifier in my hardware design. I chose nRF52832 as an MCU. In nRF52832 datasheet, it is mentioned that the pins from P0.22 to P0.31 have...
Hi,
We are currently developing a Zigbee network based on nRF52840.
One of our devices was specially designed to contain 8 endpoints. But when an active ep request is...
Hi,
I'm using the BLE_app_interactive example as a starting point for my prototype (with SDK_17.0.2 and SoftDevice s132 ). I am using nRF52DK to read and write data from...
Hi
Im trying connect two peripheral devices through UART
The example project I used is "examples/peripheral/uart"
But i trace the code, it seems that the driver layer...
Hello,
I've been using nrfx UARTE driver on the nrf5 15.2.0 SDK on a nrf52832 and nrf52840 SoC and noticed that during the boot-up the first byte being sent is 0xFF.
Is...
Can I remove resistor R29 (ENCHG) on the ADP536 to disable the charging function and plug my 3.3V supply into the battery connector?
i.e. use the ADP536 for the power management...

Hi, Can anyone explain what the "receiver address correlation" from 2.4GHz Radio documentation means in practice? For example, what can I do as a BLE application developer...
For various reasons we need to remove the dfu bootloader to use our custom bootloader. We replace the Nordic bootloader with a temporary one that does the clean-up for us...
Hi,
We're designing a PCB for the nRF52833. We could not find a PCB layout recommendation for the chip.
We did find one for the highly similar nRF52840: github.com/.....
Hi,
We want to buy a nrf5340 module but it came with the Rev C Silicon Revision. Do you have any errata sheet for this revision? I only find Rev A, D and 1 on your web...
