adl_fcmSendData to UART1 doesn't work with timers

Legacy Open AT
1

Hi,

I am using fcm UART1 and I want to send on UART1 periodically some data. I’ve inserted adl_fcmSendData(FCMHandler,“abc”,3); in timer handler, but it doesn’t work.
What’s wrong with this call in timer? Seems that it cannot work with fcm? How can I resolve this issue?

Code:

#include "adl_global.h"

I propose you changing the text sent using “adl_atSendResponse”, on adl control handler. There are some events generating the same text. Be careful with the copy and paste.
Maybe you are already sending the data and the problem belongs to the UART configuration or something like that. Who are you triying to read the sent data?
