Which one is broken, ofono or connman or something else? There is not much configurations for both ofono and connman, Can the defect hardware particularly the system power supply caused the link down? I have only one test device, I cannot prove it. The SATA chip has a pin for power up, During the boot, a command to set the power up before ofono is running. When the link is down, either I restart the ofonod or I called the command to turn the power up again, both can bring the link back. I cannot image the chip could lose power, but if the system power supply is not stable in some stage too low to support the SARA chip, will it trig the power down? I talked to the hardware engineer who rejected that it did not make sense because WiFi was running fine, he is pointing the figure to the modem manager and connection manager. Thank you.
