4 Operation Procedures
BC950K-GL TE-B can be used alone to upgrade firmware and debug applications based on BC950K-GL.
Also, it can be used in conjunction with an STM32 Nucleo-64 development board via Arduino interface to
develop NB-IoT applications based on STM32. The following describes the operation procedures of TE-B
in different operation modes.
