Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi. We are using the nRF52 sdk v12.1 with S132 v3.0.0 on a nRF52832. Once in a while (could be after running a few hours, could be after running a week) the application ends...
Where can I find the right documentation to start understanding the Nordic Thingy FW? Do we have any design document for this?
I need to develop my own application on the...
Hello,
I'm looking for some general guidance on the following application:

Hi,
I will work with nRF51822. I installed all software tools and I connect target device with debugger.
Should I connect nRF51822 with power like battery (because I will...
I used SES and wrote a printf message at main entrance: when I run in nRF Connect I can see the message that I wrote just after I press the RESET button (OK). Still, as I...
Hi,
What is the GPIO pin state during reset, and during startup ? I have seen that it is a high impedance floating input. How much is the value of this impedance? Can I...
Hello,
We're beginning FCC certification next week and I've been creating radio test and DTM versions of firmware that can run on our hardware for the lab. Everything looks...
I am using the nRF51422 for BLE data. My antenna matching network is this:
However, compared to the DK I am getting lower gain (DK gives -50, my PCB gives -64). I have...
Hi,
I want to load both "SPM" and "http_update_ota" code separately to the nRF9160.
For that as suggested in " http://developer.nordicsemi.com/nRF_Connect_SDK/doc/0.4...
I've been trying to configure a second UART for use on the nRF9160 DK. However, I'm having some issues getting anything to send over the UART. I feel like I'm missing something...
Hi,
I use the nrfx_rtc_tick_enable() function to enable tick interrupts for the RTC.
I have a statemachine that in some states disable the interrupt and sometime enables...
