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...
As part of the Bluetooth LE course we need to setup and install the nRF BLE sniffer for wireshark. I have followed the explained steps in the course to set up wireshark to...
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...
Hi
The TWI driver has a twi_clear_bus() function but the TWIM does not.
I'm getting an I2C error, and need to do I2C soft reset. I'm doing this manually at moment but...
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...
Hi
I want to use nrf52 LATCH register.
I can see the correct bit set in the register, but I am unable to clear this bit.
I have tried NRF_P0->LATCH =0xFFFFFFFF; for my...
Hello
I am doing a PCB design using nRF51422-QFAC chip. I did based on nRF51-DK but now I would like to change for a SMD antenna (2450AT18A100 from Johanson Tech.) instead...
Hi ,
I am working on one application in which i need to stream the ADC values over BLE to the mobile App. This should happen at very high rate i.e. 1000 samples per seconds...
Hello,
I'm trying to do something like ibeacon where data is pushed to any device listening, but I want to update the advertising data from raspberry pi 3 since it supports...
Hello,
I am working on an application where the nRF51 acts as both central and peripheral. The device is in permanent connection as peripheral while scanning for other devices...
Hi
can ESB be considered RealTime transfer as soon as it has it's timeslot?
Outline of use-case:
Device advertises existenace on BLE
If there is data waiting...
I am trying to implement a REQ line protocol over GPIO to signal to the Master when it is ok to receive data. Basically, I want to pull the REQ line high when the nrf51 has...
Hello,
Ble spec says that "new alert" characteristic - field: "category ID" can have 1 or 2 bytes.

Hi,
I have ordered a PCB using the reference schematic for NRF51422 user guide.
I wanted to know whether the schematic has the required antenna design or I need to add...
Hi All,
I have a basic question about advertsing data, more precisely about device's address.
I try to disable in my advertising data, the address field but it doesn't...
Hi I followed the Nordic UART example code to read and write characteristics to a Nordic S110 nRf51822 device.
My code is the same as in writeRxcharacteristic but when...
When I'm single stepping my nRF52 application in Keil with a BLE connection I always get the softdevice_fault_handler called.
I'm using SD 132, v2.0.0 and the the parameters...
What is the maximum clk frequency that can be output on a gpio for the nRF52832 ? I want the nRF52832 to output a clk signal on any of the gpios to an external module, and...
Can anyone please suggest a simple example on initializing SAADC Driver on one pin and do a simple blocking ADC read?
Sorry for a very broad question - but rather to ask...
