XT-ZB1 Zigbee 3.0 and BLE 5.0 Coexistence Module Development Kit

Overview

XT-ZB1 Zigbee 3.0 and BLE 5.0 coexistence Module is a highly integrated single-chip solution providing Zigbee and BLE in a single chip. It also provides a bunch of configurable GPIO, which are configured as digital peripherals for different applications and control usage.

The XT-ZB1 Module use BL702 as Zigbee and BLE coexistence soc chip. The embedded memory configuration provides simple application developments.

The XT-ZB1 board is configured to run at max speed by default (144 MHz).

Serial Port

The dt_xt_zb1_devkit board uses UART0 as default serial port. It is connected to USB Serial converter and port is used for both program and console.

Programming and Debugging

The dt_xt_zb1_devkit board supports the runners and associated west commands listed below.

	flash	debug	rtt	attach	debugserver
bflb_mcu_tool	✅ (default)
openocd	✅	✅ (default)	✅	✅	✅

Samples

#. Build the Zephyr kernel and the Hello World sample application:

# From the root of the zephyr repository
west build -b dt_xt_zb1_devkit samples/hello_world
west flash

Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyUSB0. For example:
```
$ screen /dev/ttyUSB0 115200
```
The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
Then, press and release RST button
```
*** Booting Zephyr OS build v4.2.0-1031-g63c9db88d01a ***
Hello World! dt_xt_zb1_devkit/bl702c10q2h
```

Congratulations, you have dt_xt_zb1_devkit configured and running Zephyr.
