Succesfully flashed Panamalar NX-SM200

As described in this issue the procedure for flashing the Panamalar devices is a bit different. After starting the start_flash.sh do NOT connect any laptops/smartphones etc to the vtrust-flash Wifi network. Instead just skip step 1 and start with step 2 to connect the Panamalar device to the Wifi network.

Template I slightly modified the known user template because the Panamalar device does not have any user defined GPIO’s available. The Panamalar device also has 2 LED’s, a blue one and a red one:

Blue flashing: not connected to WiFi and/or MQTT broker Blue continuous: connected to WiFi and MQTT broker; device is switched off Red continuous: device is switched on

I’m not sure how the LED’s are connected to the GPIO’s. Using GPIO4 as shown below seems to work, but two LED’s connected to one GPIO seems strange to me.

It looks like Panamalar re-designed this smart plug circuitry and used different GPIOs. I just received a new batch of the Panamalar SM-SX200 smart plugs and the Template above doesn’t work with the new plugs anymore.

My preliminary result for a new template is:

{"NAME":"NX-SM200","GPIO":[17,0,0,0,52,132,0,0,0,130,21,134,0],"FLAG":0,"BASE":45}

Notice the different MAC, FlashChipId and FlashChipMode.
