Hello,
there’s a section in the NRF9160 specification (11.1) that calls out that VDD_GPIO should be applied after VDD has been applied on power up and VDD_GPIO should be...
Hi,
I am sending firmware image using my DFU master. The image needs to be divided into data objects each of 4096 bytes and then those again into 244 byte BLE packets. So...
Hello,
I'm trying to connect to nrf connect with the nrf9160 DK. I am using an Irish vodafone NB-IOT sim to establish the connection. This sim has an access control list...
Hi,
I have a question regarding a DFU update via BLE. I am using mesh sdk v3.20 and sdk v15.30 with custom hardware (nrf52840).
I have the BLE DFU working as expected...
Hi all,
I am using mesh sdk3.20 and sdk15.30.
I noticed that with the buttonless ble dfu, it is not possible to perform a DFU transfer after the device was provisioned...
I did the program using examples of glucose. But I do not want to enter passkey from central. Because there is no LCD or UART in my device. Which part of the glucose example...
I am developing firmware for my Peripheral Device (nRF52840) using S140 (v7) and SDK 15.3. In my application, I will advertise (with advert payload changes) and support Smartphone...
Hi,
How much is the expected time period from the time VDD goes above 1.75V to main()? I am using a custom bootloader and am seeing a ~4.5s (yes seconds!) delay in getting...
i'm trying to configure the nrf to rx and according to the state diagram i realized that: as the nrf is supplied and the voltage goes over 1,9V the nrf goes in the power down...
Hi, i'm using the nrf24l01 with a zynq board to use it as radiocontrol; i'm trying to configure the nrf as receiver so that i'm able to send data from another nrf connected...
