Hi Nicholas, please refer to this thread <https://stackoverflow.com/questions/29538935/why-does-unsigned-char0x80-24-get-sign-extended-to-0xffffffff80000000-64?noredirect=1&lq=1> for an explanation of the observed behaviour. QMI uses additional TLVs for LTE bands > 64. Please refer to data/{qmi-service-dms.json,qmi-service-nas.json} in the libqmi sources for details.
