  • Hello, i made a new subject, but i think is following this subject: Pymesh updates

    I have try to use the pymesh network for see how to use it. I have upgrade a lopy4 with the 1.20.0.rc12:

    rst:0x7 (TG0WDT_SYS_RESET),boot:0x12 (SPI_FAST_FLASH_BOOT)
    configsip: 0, SPIWP:0xee
    clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
    mode:DIO, clock div:1
    load:0x3fff8028,len:8
    load:0x3fff8030,len:2156
    ho 0 tail 12 room 4
    load:0x4009fa00,len:19208
    entry 0x400a05f4
    Initializing filesystem as FatFS!

      File "loramesh.py", line 61, in __init__
    AttributeError: 'LoRa' object has no attribute 'Mesh'
    Pycom MicroPython 1.20.0.rc12 [v1.9.4-81167ed] on 2019-07-15; LoPy4 with ESP32
    Type "help()" for more information.
    >>> 
    

    I have get the software in this page: https://software.pycom.io/downloads/LoPy4.html

    Maybe the LoRa object with Mesh attribute was on other folder?

    Can someone explain me my error? Thank's



  • Hi @thibault and @angie92v,

    Pymesh (Mesh subclass of Lora) was excluded from build rc12. There are some licensing issues which we are trying to solve.
    Most likely, next week, I'll make a separate pymesh firmware binary release (just latest RC+pymesh module).
    As a temporary workaround, some older releases can be used, 1.20.0.rc8-9-10.



  • I had the same problem, to fix it put the version 1.20.0.rc11 and now i don't have that error but the mesh doesn't detect any neighbor and don't know how fix that
