Hello,
4 of 5 times when i want to connect to my firmware using RTT the firmware crashes.
Commands that i use are:
terminal one: JLinkExe -if SWD -device nrf52 -speed 4000 -autoconnect 1
terminal two: telnet localhost 19021
Now why i write…
Hi all,
I've got a single Thingy:52 (FW v2.1.0), and no DK. I'm trying to upgrade its firmware through nRF Connect on Android, but keep on running into a FW version failure (Code = 5) error whilst doing the DFU.
Can anyone enlighten me whether the…
Hello developers,
I am developing a smart padlock using nRF52832 SoC and plan to launch it on kickstarter. By far I have successfully made prototypes using HRM code as template and bluetooth module as my hardware.
Post this I wish to make a custom…
Hi, I'm building a product with use this kit www.nordicsemi.com/.../nRF52-DK and I would like of know how write the firmware in others CIs to can use in my circuit board. I am beginner with this plataform. Thanks.

Hi there,
We've had our own custom controller made, based on nRF52 (Rigado BMD-300 module).
In the last half of January we'll have a baseline firmware working, but we need someone to continue the work on extended functionality (such as OTA firmware…
Hello,
I have a custom board which has NRF52832 SOC(i.e. main MCU) and another ARM Core-M0-based MCU(i.e. target MCU). These two are connected over I2C. I wonder how to download firmware of target MCU from NRF52832 SOC to this target MCU over I2C?…
Hi,
Is there a way to do OTA secure firmware updates with a Windows application?
I've got some users without Android or iOS phones that want to do updates - and they're on Windows so Web Bluetooth isn't an option yet.
It seemed that the nRF devtools…
Hi. Can we develop and use our own firmware for any of the Nordic's beacon? Or do we need to mandatorily use firmware given by Nordic with beacon and modify them as much as possible?
Hi
I need to develop PC software to Discover, Connect, Get and Set data to the nrf device that we developed.
I am using the MCP and nrf connect but my client want to have his own app.
Where can I get the communication protocol for the dongle…
I Programmed my beacon devices with this firmware:
ble_app_beacon.zip
the only app that can find my beacon on ios is nrf connect. in this firmware the uuid is this:
#define APP_BEACON_UUID 0x01, 0x12, 0x23, 0x34,
0x45, 0x56, 0x67, 0x78,
0x89…
Hi :)
I developed my Bluetooth app with MBed and the RedBear BLE nano module. My jumper wire installation connecting an stm32 with the module is working great and everybody is happy.
Now I need to make a design in and I want to put the my host controller…
Hi, after I updated my MAC OS X to the latest version EI Capitan, I found my JLink commander cannot connect to the PCA10001 board again even with the Jlink commander updated to the latest. After some search work, I speculate that the JLink OB firmware…
Dear Developer Zone
I have searched now a lot in the Internet, mostly the say it's possible to reprogramm the Firmware of the nRF51822. I have such a chip and a JLink Debugger. Is it possible to download the sniffer .hex File via the JLink Debugger…
I'm using JLinkExe ( J link commander ) for Linux to flash the application firmware on NRF51822_QF_AA target. The following have worked so far, but I'd like to confirm and have some doubts. The typical JLinkExe session invoked as root on my Linux system…
I'm doing some work with the nRF51822 smart beacon kit. I tried to do an over the air firmware update of the application, but kept getting dfu invalid state (2) errors after progress got to 1%. I tried to reupload the original precompiled hex application…
Hej,
that might sound like a dumb question, but what is the minimal setup to program an nRF51822 SoC using the SWDIO/CLK ports?
What external hardware is required?
What software is required to built and flash a new firmware?
What about…
Hello,
I have downloaded the software related with the "nRF51822 Bluetooth Smart Beacon Kit" in order to modify typical iBeacon's parametres such as UUID, Major ID, Minor ID. But I'm thinking about if would be possible to modify for example the advertising…
Hi,
I'm writing the f/w upgrade function.
The device is NRF51822, and I use nRF51 SDK_v5.1.0.36092 with s110_nrf51822_6.0.0_softdevice.hex.
I refereed to the example "device_firmware_updates" with 2 banks, but put the processes in my executing…
Hi,
I created firmware to nRF51822 Development Kit but I have a problem with connection. PCA10004 board is programmed to advertising packets whole the time and measure battery voltage level every hour (APP_TIMER_PRESCALER 8, BATTERY_LEVEL_MEAS_INTERVAL…
We are looking to understand the internal working of the nRF51822 firmware (MEFW_nRF51822_0.9.0_firmware.hex). If someone can share the original code or the basic block diagram of its working that would be great.
Thanks
