Hi,
I've recently switched some prototype code from using MQTT to a custom UDP-based protocol. What I noticed is that if I have the unit sleep for longer periods of time...
Is it allowed and possible to change the configuration of one pin from input to output chararacteristic (and back) during the normal work flow. I need this possibility for...
Howdy,
To achieve the lowest possible power consumption on the nrf9160, it is noted that it is necessary to disable the UARTs that are not used, when in sleep mode. However...
I'm unable to write a softdevice to my nrf52840, can someone please point me in the right direction?
I was able to program the board just fine using nRFGo Studio, but I...
Hi, I am using Adafruit BLE sniffer with nRF51822 v2 firmware and I am sniffing BLE packets in Wireshark. I can see my devices advertisement data when my device is in the...
Hello,
We are using the nrf connect Android app in order to scan and connect to ble peripherals.
The scan procedure is executed perfectly as we can identify and connect...
Hi In v5 one can advertise in le_coded and then a central can connect off the resulting AUX packet.
For the AUX_CONNECT packet the inter-packet delay is T_MAFS which is...
When I read Objective Product Specification v0.7.1, it seems external pull-up resistors are required.
However, when I use TWIM without them, it works out.
Do I need...
Hi Everyone,
I am using nRF52832 with SDK v14.2 and SD v5.0.0 on a custom chip.
Recently i included DFU support to our application. It turns out that secure bootloader...
Hi, I'm new to nRF52480 and Nordic SDK. It is first time for me when SDK has one big config file sdk_config.h. I started playing with examples (LEDs, serial I2C) and get it...
I am developing a PCB that contains this schematic, I can run the sw code on the nrf52832 and use the pinout, but I can't connect to nrf52832 via ble communication. I think...
Hi. My product uses nRF52840 as a beacon transmitting every 3 seconds at max power of +8dBm fed to an antenna of gain 2dBi. Is SAR testing needed for my product? Product is...
Hi,
In our application Csense driver is used.As it can be implemented using COMP and SAADC,due to mentioned limitations for COMP we opted to use SAADC.Only AIN7 is used...
Hello, I have a time critical project that requires a unique service routine, thus a specific 128 bit UUID. I am following the tutorial on custom services but it does not...
