Accidental AT+KUSBCOMP=1 lock on custom HL7812 board without physical USB lines

[jyijyi]

Have yoy contacted distributor?

To enter AT command in uart0, you need to set at!switracemode to RnD mode or AT mode first

Using two UARTS setup for HL78xx, where one UART is used AT commands and a second for PPP traffic

How about setting like this? I can use both UART as AT port: ati3 HL7812.5.7.3.0 OK at!entercnd="A710" OK at+Switracemode? +SWITRACEMODE: RnD,9,2,0 OK AT+SWITRACEMODE=AT OK at+cfun=1,1 OK
