Hello,

We are having an application that uses UART0 for other MCU communication and UART1 for sensor communication.

With Chip TLRS9218A can we use 2 channels UART0 and UART1 for above application?

I'm getting the MCU reboot error when using both UART0 and UART1.

it can use both of them at same time,visit wiki and download driver SDK http://wiki.telink-semi.cn/wiki/chip-series/TLSR921x-Series/,when driver SDK port ok,then port to Zigbee SDK.

I wrote more for uart1 . handler

But I can't use both UART0 for MCU another and UART1 for Sensor

please do not use zigbee SDK api to init two of uart,you should start with driver SDK http://wiki.telink-semi.cn/wiki/chip-series/TLSR921x-Series/,when driver SDK port ok,then port to Zigbee SDK.

I have consulted the SDK driver section but it is the same as Zigbee's SDK

Currently, I can only use 1 UART.
I have to SWITCH between UART0 and UART1 for my application

Hi，

You can use both of two uart for you application,try use driver SDK to port you appliction frist.

Hello,

I can't use UART0 and UART1 at the same time right?

That means I will have to switch 2 channels UART0 and UART1 to use alternately, right?
