I am having some problems with the new board I received. Initially, I couldn't connect to the DUET WiFi server, so I upgraded to the latest firmware, which was DuetWiFiFirmware-1.17b.bin, DuetWebControl-1.14.bin, and DuetWiFiServer-1.03-ch.bin. The microcontroller had a hard time communicating with the WiFi chip and I saw a lot of trying to connect at XXXXXX baud: failed errors , but eventually it connected and the WiFi and server firmware loaded. The web server didn't initially come up, but after trying for about half a day, it magically came up all on its own. It has worked flawlessly for about 4 days, then this morning, it quit working again. I checked on git this morning and noticed a new Firmware for the DuetWiFi board and Duet Web Control, so I downloaded them and tried to install them this morning. I had no problem loading the Firmware on the Duet WiFi board, but when it came to the WiFi chip, the microcontroller just can't communicate with it.
I have been a systems engineer for over 20 years and have a lot of experience fixing buss and communication problems with I2C, SPI, 1-wire, etc…there seems to problem with the buss or the bit banging routines. It is also possible there could be a bad (cold) solder connection under one of the chips on the SPI buss...
I would like to hear your thought on the problems I am having,I am pretty frustrated at this point... Plaease send your responses to firstname.lastname@example.org
