Dear Developers! Currently, the only tool I have found this information: http://users.atw.hu/helvei/UAP3801E.rar?atw_referer=http% 3A% 2F% 2Fmobil- telefon.vatera.hu 2Fmobiltelefon_tartozek%%% 2Fegyeb 2F4_db_huawei_ap_femtocella_mobil_bazisallomas_1459406466.html This is a power point presentation, the pages visible to a certain set of procedures. Although I do not know how much help in the development, but I share with you. Consulted during a programmer who is interested in finding a "reverse engineering" and curious about the possibility of the device, the communication. I am confident that if he succeeds, much of the project promotes the development of OpenBSC. Regards, bthomyka
