Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hi,
At command, I'm sampling ADC for a short period of time. What I noticed is that the current consumption of the chip goes up 2mA, even after the sampling is stopped...
Hi,
What is the actual difference in hardware between the two chips? I know they support different soft devices but is there any actual difference in the hardware? Or is...
Does having monitor mode debugging or using RTT print statements increase the quiescent current of the nRF52 even when the debugger isn't connected? I am using S132 SoftDevice...
I'm in the process of porting code from a PCA10000 rev2 board to a custom board, using the ISP130301 integrated MCU (contains a rev3 nrf51822 IC). I'm using nrf51 SDK 6.1...
Hi,
I use an nRF51822 QFAC A1 and my goal is to disable BLE in a powerdown mode, then when I press the pushbutton I want to restart BLE.
Tried using BLEDevice::shutdown...
Hi,
I'm using nrf52 dk(PCA10040). I want to disable the SAADC between readings to save power. I am calling the function nrf_saadc_disable() to do so. It seems to disable...
Hi,
I am having some trouble to make NFC Tag emulation working with "ble_app_hrs_rscs_relay" example application in the nRF5 SDK v11.0 on a PCA10040 board. Actually I did...
Hi all,
i have a little problem with the #define NRF_LOG.
I have this warnings, and i don't know why.

I am trying to advertise my eddystone UID,TLM and URL frame on advertisement. Here by board is in peripheral mode.
I used radio_notification_init() function where i have...
Hi
We are developing software for the nRF51 with Keil under VirtualBox. Previously we used the PCA10000 dongle with the Master Emulator and MCP without issue. Now, with...
It seems like there are several asynchronous things that happen and it's unclear what had proprioty over each other. I assume interrupts asynchronously interrupt everything...
Hi,
I use the nrf52 dk(PCA10040). When monitoring the current consumption of the advertising with the DCDC enabled, we see some current spikes. Why?
Here is two screenshot...
I modified the code of ant_background_scanning_s212_pca10040 to make it works with s310 on nRF5144 xxaa.
The code works fine, but loose a lot of RX packets (more than 80...
