nRF5 Multi Sensor Board (12-14€)

@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?

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.
