Hi,
I got this error, what wrong???Using precompiled core
Linking everything together...

Error compiling for board MyBoardNRF5 nRF51822.@mika sorry I think I forgot to include in the code the instruction :
In the WInterrupt.c file before the GPIOTE_IRQHandler you need to include a weak attribute so it can be overridden :
__attribute__ ((weak)) void GPIOTE_IRQHandler()It's the file linked in your error message :

Dear colleagues!
I have this nice nRF51 sensor tag. May be you can help me to understand the limitations of this board.
I want to make wireless water tank cap opening sensor. I have another device (my own development) with bluetooth BLE interface, with external power supply which will act as receiver.And I'd like to use nRF51 as wireless battery powered cap opening sensor. As I can understand in Aliexpress-version it is not possible (short battery life). I think I must make new firmware at least.
But is it possible to do onboard ?- Switch off BLE transmission but still make onboard analysis of fuel cap movement with MPU6050
- When cap open event is detected (my MPU6050 data) - wake up BLE and start transmission.
Or may be Low power BLE mode will shut up MPU6050 transmission too and this mission is impossible?
Many thanks!

@mechand use MySensors you can send a message only when you want without any tricks with BLE.
And BLE/radio and accelerometer are 2 different things so you should be able to shut down BLE and go to sleep after configuring the accelerometer to generate an interrupt if it detects movement. But if you want to stick to BLE the solution is probably to advertise with big intervals, current battery drain is not due to BLE but due to a hardware problem with pin interrupts. -

I got some of these from ebay, but they're fitted with nrf51802 QFAAA1 instead of a 51822. I can't find the memory sizes etc. for the 51802 - can they be used ?
@artag The nRF51802 QFAA has 256k Flash and 16k RAM. It is pin to pin compatible with the nRF51822QFAA in the QFN48 package, 6x6 mm. Note that some of the parameters for the nRF51802 are slightly looser then the nRF51822. (Current consumption, wakeup time, sensitivity)
-
Are people still happy with / using this little device?
-
Looks like no one is active. I am also curious.
-
Im using now mainly NRF51 and SAMD21 MCU, TutuApp Onlinesbi aadhar card both of them have lot of advantages FLASH, interrupt on all pins, consumption.....

Hello, i have an nRF51 Sensor Tag Module. But i couldnt find sensor examples which is writing on Arduino. Also I need an bootloader but, i couldnt find any. Is there anyone have these?
https://github.com/sandeepmistry/arduino-nRF5
Install this and find libraries for whatever sensors you have on that board.@basaksts said in nRF5 Multi Sensor Board (12-14€):
Also I need an bootloader
No, you really don't. You need ST-Link, or J-Link SWD programmer/debugger. Connect it to SWDIO, SWCLK, 3.3V and GND and program it using Arduino IDE.
