This is fork of Lumi Router JN5169 firmware for use with the LM15-SP-WM module used in the Xiaomi Smart Plug (ZNCZ02LM).
Also it can be used with any other JN5169 based module.
The only difference is the ability to reset the device using a button on DIO 0.
In the original firmware, all control takes place only through the serial port.
- Download JN-SW-4107 and install
- Connect using JP1 to your USB-TTL according to table below:
| LM15-SP-WM (JP1) | JN5169 | Function | USB-TTL |
|---|---|---|---|
| 1 | DIO 28 | TXD0 | RX |
| 2 | DIO 29 | RXD0 | TX |
| 3 | DIO 22 | SPIMISO | GND |
| 4 | DIO 9/39 | VDD | 3.3V |
| 5 | DIO 3 | RESETN | --- |
| 6 | DIO 21/39 | VSS | GND |
- Download firmware binary to
C:\NXP\ProductionFlashProgrammerand open console at this folder. - Run
JN51xxProgrammer.exe -s COM1 -f LumiRouter_20210707.bin -v -V
The device enters join mode in two cases:
- When PDM memory is erased
- Right after leaving existing network
Long (> 2000ms) clicking on BTN (DIO0 to GND) erases PDM memory. The device will restart and then automatically join.
Close JP1_5 (DIO 3) on GND to restart device.
Some time ago I found such modules based on JNN5169 on TaoBao and ordered a couple.
Initially, I planned to use them as development boards to learn and play Zigbee SDK by NXP. I soldered just such a comb for easy installation into a breadboard.
But since they are not very convenient as a development board, it was decided to make routers out of them to expand the Zigbee network.
