Dear all,
This is probably a question for Luis -
I may need to write a NMEA filter to interface to an instrument which may need to produce a specific pattern.
So Uart In -> Process -> Uart Out.
It occurred to me that I could do this on a Expressif board and I saw Adafruit have some - not expensive.
But then it occurred to me - if I could load my binary (with WIFI OTA) into an NMEA2WIFI , that already has all the peripherals and regulators and screw terminals that I would need and as it happens I have a spare NMEA2WIFI from last year before I added AIS.
So if it is possible to re-purpose an NMEA2WIFI I would be very interested - I have seen the Arduino builder etc and I used to program micro-controllers in C before I moved to VHDL
Or if there is another board which would work - I am looking at the ADA Fruit feather board , if I cannot use the NMEA2WIFI board.
All the best
Boris.
Can I use an NMEA2WIFI for something custom ?

Hello Boris,
I see no problem. You have the schematics. I do not understand why you need to use OTA. You could just flash your binary using the serial port and Arduino.

Re: Can I use an NMEA2WIFI for something custom ?
Many thanks - I will study those and thank you for making all that available.
I wasnt sure if Arduino would work but that would be perfect for my needs.
(The OTA update would be a bonus - I was thinking if I need to change things on the boat I could do so "wireless") -
But what you suggest is simpler and therefore probably better so I will try your serial line method.
Can I reflash the NMEA2WIFI Binary if needed or will it remain custom for ever once I change it to my simple binary ? Not a big deal , just curious.
Aside - I think I need to construct a GPRMB message from the RayMarine ECRMB message - so I was hoping I could use the nice NMEA2WIFI platform for that as my Winter Project.
Best regards and thanks for the confirmation !
All the best !

Hello Boris,
If you flash with a custom binary and want to return to nmea2wifi you the same problem as if you need to change the ESP32 module in a TH unit. There is a small OTA program in the forum that you can flash the "destroyed" EEPROM and then you can do a OTA flash of the nmea2wifi binary.
If you need more information write me.
