Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hello,
I want to request AGNSS information from nrf cloud services using my nRF9151DK board. As a first step, I flashed the nRF Cloud multi-service application onto my DK...
Hello,
I am using the nRF52832 on a custom board, with SDK 15.2 and SD132 v6.1. My BLE application uses the SAADC to measure VCC voltage every 6 hours. I am using an app...
Hello Sir,
I am Working with nRF52 DK Development board. My application based on BLE. I want BLE stack for Scanning mode and also tell m,e how to operate with mobile apk...
How to
1. increase advertising frequency - Which BLE GAP parameter should be updated?
2. increase RSSI signal strength - My device is not battery operated, so there are...
Hi,
How can I make the modem start a hot fix after rebooting the nrf9160?
I am getting a GPS fix, then powering down the modem with CFUN=0, which should be saving the...
Hello, I recently bought a nRF52840 with the intention of using it as a substitute for UART wired communication. What I want to do is send and receive messages between my...
I carried out following steps:
Application was using SDK 11.0.0 for nRF51 SoC
Ported SDK version 12.1.0
