BC660 wakeup using UART

Technical Subjects
1

I have a problem waking the BC660 module using UART.
I do not have access to the PSM_EINT pin.
I can access PSM.
I have set AT+QSCLK=1 .

When I want to exit deep sleep mode I send the AT command but never get the OK response.
I use baudrate 115200.
Please help me.

AT+QCFG=“wakeupRXD”
AT+QCFG=“wakeupRXD”,1

Thank you,
but that was not sufficient.
I use AT+QSCLK=1
Is that correct?

Yes, you are right;

AT+QNBIOTEVENT=1,1 //Enable PSM status URC reporting
AT+QATWAKEUP=1 //Enable hibernating URC reporting

I have set:
AT+QNBIOTEVENT=1,1
However for:
AT+QATWAKEUP=1
I get ERROR

sorry

AT+QCFG= “dsevent”,1 //Enable hibernating URC reporting

I have sent the following:
13:46:31 → [TX] AT+CEDRXS=1,5,“0101”
13:46:31 → [RX] OK
13:46:31 →
13:46:31 → [TX] AT+CPSMS=1,“11011111”,“00000000”
13:46:31 → [RX] OK
13:46:31 →
13:46:31 → [TX] AT+QSCLK=1
13:46:31 → [RX] OK
13:46:31 →
13:46:31 → [TX] AT+QCFG=“wakeupRXD”,1
13:46:31 → [RX] OK
13:46:31 →
13:46:31 → [TX] AT+QCFG=“dsevent”,1
13:46:31 → [RX] OK
13:46:31 →
13:46:31 → [TX] AT+QNBIOTEVENT=1,1
13:46:31 → [RX] OK
13:46:31 →
13:46:31 → [TX] AT+QCFG=“slplocktimes”,1
13:46:31 → [RX] OK

But still it doesn’t wakeup after deepsleep. I send AT several times but no OK is received.

Is this the latest version:
15:25:29 → [TX] AT+CGMR
15:25:29 → [RX] Revision: BC660KGLAAR01A04
15:25:29 → [INFO] ModemGetVersion: BC660KGLAAR01A04

Hi Andreas,

Did you solve the problem? I face the problem too. Sometimes the modem wakes up, but most of the time I don’t have any reaction.

Please provide the complete log, including entering deepsleep and sending AT failed to exit deepsleep

Hi All
I’ve been using the BC660 for over a year and it never misses a beat. I don’t touch the config at all and use the default baud rate.
The only write commands I do are ATE=0, AT+CFUN, AT+NBAND, AT+CPSMS and the modem goes in and out of sleep mode easily.
But Note… You can’t use VDD_EXT, just tie VIO_SEL low and use 3 - 3.3V logic (otherwise the chip sleeping will cause it to wake up)

Yes, the module goes into deep sleep and VDD_EXT changes the power down to 0V
