I just tried to get it running but I get the following error:
Oct 15 12:46:20 swi-mdm9x28-wp user.info Legato: INFO | supervisor[842]/supervisor T=main | app.c app_Start() 3420 | Starting app ‘UART’
The cdef file looks like this:
sources:
{
uart.cpp
}
requires:
{
device:
{
[rw] /dev/ttyHSL0
[rw] /dev/ttyHS0
}
}
My setup looks like this:
I want to send a test message from the module to Putty using UART1.

What is the return of at!mapuart?

root@swi-mdm9x28-wp:~# ls /dev/ttyHS*
at!mapuart?
!MAPUART: 1,16
I already removed this line in the cdef file:
/dev/ttyHSL0
I also ran the following command:
root@swi-mdm9x28-wp:~# stty -F /dev/ttyHS0 -a
resulting in:
speed 0 baud;stty: /dev/ttyHS0

The last couple of lines of the logread tell me that, in the sample you’ve shared here, the condition:
COMPONENT_INIT{
if (le_arg_NumArgs() >= 4){
... }
is never met.

You need to set
At!mapuart=17,1
And then “at!reset” to reset the module.
After reboot, you should use /dev/ttyHS0 for uart1 as data mode.

After I did what you supposed this is the output:
root@swi-mdm9x28-wp:~# microcom /dev/ttyAT
at!mapuart?
!MAPUART: 17,16

Yes, 17 means uart1 in data mode

But it’s not the same output as you suggested (17,1)
The log still looks like the one before.

Please download the AT commadlnd user guide and read at!mapuart.
Btw, how do you start the application?

I already did that.
Usage:
• Execution: AT!MAPUART=<service>[,<uart>]
Response: OK
Purpose: Map the specified <service> to the specified <uart> (if no <uart> isspecified, UART1 is used).
• Query: AT!MAPUART?
Response: !MAPUART: <service (UART1)>[, <service (UART2)>]
OK
Purpose: Report the current mappings for both UARTs.
•Query List: AT!MAPUART=?
Purpose: Return the command format and the supported parameter values.
Parameters:
<service> (Service to map to a UART)
• 0—UART disabled
• 1—AT command service (Note: Not available for UART2)
• 2–3—Reserved
• 4—NMEA service
• 5–15—Reserved
• 16—Linux Console
• 17—Customer Linux application
<uart> (Physical UART)
• 1—UART1 (Default)
• 2—UART2
How can it be 17,16 when I run
AT!MAPUART=17,1
OK
I start the app like this:
root@swi-mdm9x28-wp:~# app start UART

If you want 17,16 for at!mapuart, you need to type
Also, you shoud not use “app start”
tadera

I don’t want 17,16.
Can you be a little bit more concrete about how to set it to 17.1 and why I should not use app start?
jyijyi
October 15, 2020, 2:31pm

Query and execution are different
• Execution: AT!MAPUART=[,]

If you use app start, you cannot pass argument to it.
Did you really read the document inside the app?
