hello,
I used NRF52832 as a ble gatway.Now i have a trouble that the received signal strength is jumping about 2dBm when the chip loaded program.I test it with Spectrum Analyzer...
Hello! I am trying to prototype a DFU solution that works well for our application. We want to build a network with both normal Mesh devices and with friend nodes (once that...
Hi,
for my PCB, i'm using an NRF52832 as SPI slave, i send an array of 4 bytes {0xA5,0x00,0x01,ff}, but my SPI master receives always a byte (0xff) before 0xA5.
this...
Hello everyone
I have kind of a basic question.

Hey all,
We’re trying to figure out the best way of keeping our nRF52 (or 51) based design in the lowest power mode possible while sitting in inventory.
Currently, our...
Greetings,
I have 12 sensors each of which is located on an nRF52832 board. I need to collect the sensor data at 50Hz (10 bytes for each sensor).
For some reason I can...
This one is throwing me for a loop.
We just did a small build of 40 devices based around the nRF52832. 1 device out of those 40 is behaving very strangely. When the device...
