This is an example based on mbed-os cellular APIs that demonstrates a TCP or UDP echo transaction with a public echo server. Included TPB23 NB-IoT module which is can use LGU+ in Korea.
This example is showing how to use the NB-IoT(SECOM TPB23 module) of LGU plus network in Korea. The NB-IoT module' seller provided a document on how to start based on Mbed OS 5.11. (Created by CodeZoo) This guide has been supported to the latest os version which included 5.12 ~ 5.15.
- if you need specific version of Mbed OS, please revision of TPB23_Driver and check it out.
- Pelion ready example code is here!
Requirement
- Need to check CodeZoo's s hardware a guide.
- Need a CodeZoo's NBIoT board and development board.
- Board picture & Jumper configure
- And also can use with mbed application shield, as shown below.
Tested with
- DISCO_L475VG_IOT01A - If you are in Korea, can buy here !
- NUCLEO_F429ZI - If you are in Korea, can buy here !
1. Import the application into your desktop
mbed import http://os.mbed.com/users/Daniel_Lee/code/mbed-os-example-cellular-TPB23/ cd mbed-os-example-cellular-TPB23
2. Compile and program
mbed compile -t <toolchain> -m <TARGET_BOARD>
(supported toolchains : GCC_ARM / ARM / IAR)
3. Download binary to a target board
4. Result
