Hi there,

would this work for the use with openHaystack? NRF52832 @aliexpress what would be the smallest yet cheap devices wich would work?

Thanks a lot!!

currently there is no firmware for that model. In my opinion esp32 is still the best option you can have, and it costs half of the price of the NRF52832 (link)

Found these cheap bluetooth beacons using nRF51822 : https://aliexpress.com/item/1005003671695188.html

Using a flasher (ST-LINK/V2) it should be possible to flash the nRF51 firmware (https://github.com/seemoo-lab/openhaystack/tree/main/Firmware/Microbit_v1) onto it. Haven't tried it out yet, though.

You can flash them with ST-link v2, but you need to convert it to a J-Link using the Asshole.bin firmware from here first

Then you can use the Jflash software.
