Pysense looses connection to wipy - wipy reset
i have a Pysense board updated to 0.0.7 firmware. The corresponding wipy runs on 1.10.0.b1. After some seconds (sometimes 3, sometimes 5 or even 7 heartbeats of the wipy (blue led)) the wipy stops working. Also the (for short time enabled) connection over the serial port fails and i can only reset the wipy. Then it starts over again. some heartbeats and then failure. The serial port shows me that after the reset everything seems to be ok:
rst:0x1 (POWERON_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)

rst:0x10 (RTCWDT_RTC_RESET),boot:0x17 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
mode:DIO, clock div:1

MicroPython v1.8.6-839-g536c958c on 2017-11-15; WiPy with ESP32
Type "help()" for more information.
Then I am able to use the REPL (i.e. 2+2 >>>4 ...) for some seconds and after that the wipy stops and i have no connection any more. Reset starts the process over again, but it only works for some seconds.
For me it seems to be a hardware problem (firmware 0.0.4 same problem - different wipy, same problem - different computer, same problem). The used wipy runs perfectly with an usual expansion board.
I would appreciate if anyone can give me a hint what causes the probelm and how to fix it?!
Thanks in advance and greetings
Can you please first try another firmware update (we have released 1.10.2.b1).
If that doesn't help please try to format the internal flash:
import os; os.mkfs('/flash')
If that still doesn't help please email email@example.com
