Devices disconnect from Telink Flasher after a few seconds #216

I just flashed a couple devices: LYWSD03MMC B1.4, Software Version: 3.7, Sensor: SHTC3

3.7d is the firmware.

These devices disconnect fairly quickly after reconnecting. If I am quick enough I can request a confirmation change, but it does not seem to stick:

Is this a known issue?

  1. Discharged battery.
  2. Bad connection. The thermometer is far away.

Thanks. Devices sitting right next to the computer. One device did start behaving after switching the battery (even though the previous one read 73%). The other one appears to have issues, every now and then it starts up with the display flashing in random ways, and when it does connect it seems to be conflicted about its sensor:

11:57:04 AM: Hardware Version: LYWSD03MMC B1.4, Software Version: 3.7, Sensor: SHTC3 11:57:04 AM: Custom config: [5, 96, 0, 0, 40, 4, 169, 124, 49, 128, 60] 11:57:10 AM: Settings 56 was send successful 11:57:12 AM: Hardware Version: LYWSD03MMC B1.4, Software Version: 3.7, Sensor: SHT4x 11:57:12 AM: Custom config: [5, 96, 0, 0, 40, 4, 169, 124, 49, 0, 60]

Anyway thanks for your help, and thanks for your work on the firmware!!!
