Hi, I'm developing a keyboard-pcb with NRF52840. I'm doing this as a hobby and are not that experienced with integrated circuits. Anyway, I designed and produced a pcb, but...
Hello,
in cases where the LTE signal strength is extremely low, we observed that the LwM2M /4/0/2 RSRP rolls over from -128 to 127. We found that the nRF Connect SDK uses...
The at command documentation says that ENVEVAL is only available in system mode 2 (CFUN=2). Is there a reason why the command can't be run in any other mode? For example if...
I recently completed a field-upgrade path from an nRF5 SDK 17.1 application (with the legacy Secure DFU bootloader) to a fresh NCS-based firmware stack, while preserving user...
Hi, I am trying to understand the Friend and LPN behaviour. For that I am refering to nRF sample application light" and "light_switch". Below is the setup details: 1. On one...
We're using the nrf51 with the RFAxis (now Skyworks) 2401C amplifier, which is a fixed gain 20dBm amplifier. The goal is to have a longer range 'beacon' type product and the...
What would be the best BLE Library or Framework for Raspberry-pi to exchange with nordic?
I'm trying to get data from the NRF51's GATT data.
But there are no reference...
I recently was trying to test my nrf52 DK. After lot of failed attempts i was able to do DFU update over BLE and also Serial upload .
I am now trying to test the BLE UART...
Hi
According to previous answers ( 1 & 2 ), the limitation on the maximum number of devices that can be added to a whitelist is 8, and is due to softdevice timing limitations...
