I am going to develop an USB host application with low cost WiFi USB dongle on FRDM-KL25Z. The WiFi dongle is much cheaper than industrial WiFi modules.
I am not sure if anyone has similar experiences before. WiFi dongle used to be very tough to develop since most of them have proprietary firmware and other issues.
Is there any embedded system friendly WiFi dongle?
I do find RL3070 from Ralink, it seems popular in hackable WiFi equipment.
Any comments are welcome.
