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...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
Hi! I'm performing buttonless Secure OTA DFU operation on some custom boards of mine. I'm using nRF Connect v3.3.1, and at the moment I'm flashing a zip file containing my...
We have a door lock product. At first, the capacitance value of bluetooth frequency deviation was not adjusted, and then it was very difficult for apple to connect with vivo...
Hi,
I have a problem that can not receive FDS_EVT_WRITE event, but fds_record_write return NRF_SUCCESS when using FDS and FreeRTOS simultaneously on nRF52840. And FDS_EVT_INIT...
Hi,
In the ble_app_uart example I am trying to read a binary file and send it to the application using nRF52840 board. I have send 32 packets of data periodically.If a delay...
Hi. I am looking for a reference FW design for BTLE where I can define a custom Service and Characteristic where I can send arbitrary (minimal length) data from peripheral...
Hi,
In our application, LCD will occupy 150KB RAM, and algorithm will occupy 60KB, but 52840 only has 256KB ram, so 256KB RAM is not enough for our application;
We want...
To realize multi touch in hid, we need to realize get report request to get the maximum number of support points and set report request to set touch mode. In the SDK 15.3...
Hello,
I'm trying to add a third characteristic to my BLE service and when I add it, my device "fatally" crashes in Release mode with no meaningful error information ...
Hi I'm having trouble updating the firmware on a custom board using JTAG through the NRF9160 DK.
I've attached the log file from the programmer of the error I'm getting...
I loaded up the zephyr sample blinky example, compiled ok, and went to download to the nrf5340-pdk...
I got the following error dialog plus some more misc. errors (see output...
Hi
nrf52833 SDK16
The following code works fine on UART 0 but not on UART 1
The problem seems to come from nrfx_uart.c
There is no support for a UART1, so...
Hi,
I've built a project out of the USBD_ACM_CDC example in which I have added a SPI master driver. This project has a timer interrupt that will shoot off every ~500us and...
Hi everyone,
I'm a beginner with nordic development and I managed to screw up my development kit. It started when I was trying to figure out the BLE blinky app with my IOS...
Hi,
I'm working on an IoT project with NRF52832 ( S132) . I need to connect this device to mqtt over 6LoWPAN (IPv6) and run it on a button cell battery CR2032 for as long...
HI,
I am trying to connect to our cloudmqtt account where the topics are dynamically created because of which is it not possible to pre-program a specific topic.
I would...
