Hi,
I am working on programming a bootloader to have DFU capabilities. I have been using the secure_bootloader_uart example for SDK 15.3.0. I have modified the code to send...
I'd like to be able to use nrf sniffer tools (wireshark and nrf52dk) to listen to ble traffic after connection of two devices.
Is this possible?
Has anyone else done this...
I've read many similar issues that were raised regarding high SPI power consumption, looked at various examples, but can't seem to find any issue that is close to what i'm...
Hello.
When going to sleep with the BLE connection established, the WDT counter will be added. (WDT behaviour: NRF_WDT_BEHAVIOUR_PAUSE_SLEEP_HALT) At this time, my app cannot...
In the usbd_ble_uart example (SDK 17.0.2), I'd like to use the buttons handler module (the same one from the BLE Blinky example), instead of the BSP BLE button events. In...
Hi!
In our development we are using nrf52833 and for the first development phase we used the SDK 17.0.0. In that case I used the usbd_ble_uart example with s113 and it works...
Hi,
I am Using nrf52832DK and SHT25 breakout board. I can't able to read a device address using "TWI Scanner". But, I can able to scan the sht25 device address by Arduino...
Hello,
I am trying to clear reset reason when it wake-up by GPIO.
In line 163, I set RESETREAS to 0
In line 164, RESETREAS is read again.
I expect 0. But It still...
Hello,
I use nRF52832's COMP (comparator) to sample a pulse signal's voltage level.
I found when the pusle width is below like about 60us, the COMP can't get correct...
Hello,
we need to feed mono audio data into the nRF52 and we are now evaluating the possibility to use PDM. The nRF52 seems to have a useful PDM interface , and even though...
Hi,
I would like our nrf52840 to use coded phy 8x to get longer range.
The counter part are Android smartphones, old ones with BLE 4 support only, new ones having coded...
