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're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Dear all,
I'm designing a circuit that should allow powering the nRF52840 board with either an USB power supply (USB2) or a (non-rechargeable) CR2032 battery (B1). According...
Hello.
I encountered the following problem. I have an nRF52840 microcontroller that is already soldered onto the PCB board. It doesn't have any bootloader. As an example...
Hi,
We have an nRF9161DK and received our own custom boards this week. When we tried to program our custom board, the development kit disconnected from the computer and...
Hi all!
I'm in the process of trying to put together an nb-iot app on Android studios that would communicate with data from the Thingy 91 board. I've been trying to go through...
Above is the trace and the commands inserted. We were unable to get a response using the at+cops? command. Both SIM cards were active that we tested. We tested band 12. Could...
Hello everyone,
I've been working on testing PPP support in SLM 2.6.1 without cmux on my Linux host machine. However, I encountered some logs during the process: Note: For...
Hi
I have 2 BLE boards with some environment sensors on them.
I need to synchronise the 2 boards with < 1 mili second precision.
one board is configured as central,...
Environment:
I can't seem to get the one button sample to do anything... I get a steady ~1sec flash from HOST led on the npm1300, but I get nothing from pushing SHPHLD...
Hi.
I have following error:
Here is my prj.conf :
I would like to avoid using CONFIG_SHARED_INTERRUPTS.
Only GPIOTE0 is on IRQ number 11 so I couldn...
I have an EC11 rotary encoder wired to my nRF52840 and I am trying to get readings from it using the sensor API. However, I'm having issues with (seemingly) garbage data....
Hello,
We are currently implementing a custom DFU process for one of our client. They need to be able to upgrade the cores images, which are read from an SD-card. We already...
Good day. We ended up getting a bootloader based on the NRF5 using the Serial Recovery method and a non-upgradable bootloader. The update is coming from a microcontroller...
I'm working on a linux driver for nRF7002 based on the experimental linux driver: https://github.com/NordicPlayground/nrf70-linux-driver . This is being done on linux 5.13...
Is it possible to somehow set a lower charge current than 32mA for the whole charge cycle or force trickle charging for the constant current charge cycle? The issue is that...
I have a GSM application connecting to MQTT that worked previously refuse to work when I picked it up again to improve on it.
To make sure there isnt a problem in my firmware...
