[FX100]Problem: AT+IPR=0

IoT Gateways Legacy FX/FXT series
1

Hello,

I’m trying to send AT command from a microcontroller to the FX100 trought the uart 1, but i can’t manage to set well the uart parameter.

The reponse to AT&V is :

AT&V
Q:0 V:1 S0:000 S2:043 S3:013 S4:010 S5:008
+CR:0 +CRC:0 +CMEE:0 +CBST:0,0,1
+SPEAKER:2 &C:1 &D:2 %C:0
+IPR:0 +ICF:7,5 +IFC:2,2

When i send AT+IPR=115200 from the usb, here the result.

AT+IPR=115200
OK

AT&V
Q:0 V:1 S0:000 S2:043 S3:013 S4:010 S5:008
+CR:0 +CRC:0 +CMEE:0 +CBST:0,0,1
+SPEAKER:2 &C:1 &D:2 %C:0
+IPR:0 +ICF:7,5 +IFC:2,2

OK

It the same for +ICF and +IFC, i cannot manage to change the value.

Here is the result of AT+WMFM?

AT+WMFM?
+WMFM: 0,2,1,1
+WMFM: 0,2,2,0
+WMFM: 0,2,3,1
+WMFM: 1,2,4,0
+WMFM: 1,2,4,1

OK

Thanks for your answer,

Best regards

Hello

Do you mean you send the AT+IPR=xxx on USB uart and expect that UART1 data rate will be updated ?

I don’t have it to hand at the moment, but doesn’t the AT Commands Manual specifically state that these are ignored on the USB interface… :question:

FX100/Q2698 doesn’t support UART1 autobaud.

AT+IPR=? on UART1 (with Firmware 7.53 beta release) returns
+IPR: (),(300,600,1200,2400,4800,9600,19200,38400,57600,115200,230400,460800,921600). Note the absence of 0 in “(list of supported s)” parameter

Thanks for all the reply.

I was making a mistake, but now it’s ok.

I’m able to receive and send data trought uart, and yes is very useful to well read the documentation…
