I have been using the Seeed Studio Halow board but they are out of stock so embarked on building my own. The Seeed board runs well on ESP32 as the host which is what i plan to use in my final application.
Finding the same Quectel module is proving to be rather difficult, its the FGH100M-H FGH100MHAAMD based on whats etched in to the top of the module. So I have been looking at the FGH100MABMD instead which appears to be in stock at a few distributors.
I am in the middle of designing the board and using the Seeed board as the reference design as its proven to work. The Seeed board pulls GPIO0 to ground with a 10k resistor but the module I am using (FGH100MABMD) doesn’t seem to have such a GPIO. Will the ESP32 code work if that pin is omitted?
Alternatively, are there any other modules (USA frequency) that are known to work with the ESP32 build?
Thanks.
