PSM mode trouble #134

Open Markush7 opened 3 years ago

Markush7 commented 3 years ago

Hello, I can enter the PSM mode and set the timer T3412 and T3324 in LTE-M or NB-IoT. All the LEDs are off. But after a few seconds, the SIM7000g wakes up automatically. when I read out the timer settings from the network, the network has taken over the timer.

Anny Idea why the SIM7000 wakes up automatically? Is this a general issue?

My AT commands:

SerialAT.println("AT+CPSMSTATUS=1"); delay(500); SerialAT.println("AT+CEREG=4"); delay(500); SerialAT.println("AT+CSCLK=1"); delay(500); SerialAT.println("AT+CPSMS=1,,,\"01000111\",\"00000000\""); //Enable PSM mode and set the specific T3412 (70 hours) and T3324 (0 min)

I have already tried it with another library (Adafruit_FONA). With the same result.

Thanks Markus

What network are you using to allow the PSM mode? I don't think it works with Hologram
