Since the Mini 2MP is obsolete
Via this linkhttps://www.amazon.com/Arducam-Module-Megapixels-Arduino-Mega2560/dp/B012UXNDOY only can buy Mini-2MP-Plus
The official git source https://github.com/NordicPlayground/nrf52-ble-image-transfer-demo and Jimmy https://github.com/jimmywong2003/nrf52-ble-image-transfer-demo/network fork seem can't normally work with the APP source https://github.com/NordicPlayground/Android-Image-Transfer-Demo
I already test the Mini-2MP-Plus device with Arduino and confirmed the camera work.
But run the demo whatever official or Jimmy fork the APP after connect have not any image display.
Thanks
Best Regards
