Hey devs!
We'd like to add additional fields in the manifest.json when generating (or after generating) the zip file for DFU. We need these fields to make additional compatibility...
Hello,
I am using the nrf 52 dk with the soft 3.00. I am doing the Beacon Transmitter Sample Application from infocenter.nordicsemi.com/index.jsp.
I was able to compile...
Hi
I am using nrf52832 QFAA-R.
I wanted to know if there is a difference between SPIM current when SPIM is:

Hi all,
I am testing out the BLE_APP_UART example on a NRF52DK and I am using SDK13.0 (PCA10040, S132).
I have change the app advert timeout to be 10 seconds.
I am...
I am trying to combine both the SAADC and BLE libraries to be able to read a value from my sensor on the analog pin and then send it over Bluetooth LE to a central dongle...
I plan to merge the protocol sack and the application. At the same time download in batch to 52832 by using the SWD. But the tool(nRFgo Studio) offered officially is not fit...
Using existing examples in SDK13, I prepared ADC sampling app which works fine in ESB TX mode. Works well sending frames at 10ksps, and I can also put it to 'standby mode...
Hello! I have to connect some microphones (adafruit MAX9814) to a nrf52 board and I have to choose some beacons. My idea is to have a tiny solar panel that charges a capacitor...
I have a custom nrf52832 board. I have changed the UART TX and RX pins to P0.3 and P0.4 respectively. If the pins are floating, then nrf52832 stops advertising,If something...
I use example ble_app_hrs_pca10040_s132 with SDK12.2.0 to test bonding function.It works as a server and it is bound by client. But I fail to bond. It seems that example has...
Hello,
I try to declare two instrances of TWI0 and SPI1, and I include the both sdk_config (sdk_config_spi and sdk_config_twi) in the same file, but I always get the error...
Hi,
We designed the circuit followed the reference circuit(QFN48), but we always failed in the 8kv ESD test.The CPU always reset while ESD testing.
The 8kv ESD power...
