Issue on M66 modem

issues on M66 modem

  1. we got “ERROR” on the command AT+QIACT for vA2123 HW and M66R01A12 firmware, no problem if using vA2124 HW with same firmware version .
  1. I was noted that a fresh M66 doesn’t send URCs on power up/down until the command AT&W (more exactly, I send the multicommand string “ATV1X0;+IPR=115200;+IFC=0,0;&W”). How does this command affect URC?

  2. If VDD_EXT (pin 24 of M66) is UP, does this mean M66 is fully initialized and ready for all operations?
