I recently bought 2 Wio-E5 Mini dev boards to create a P2P IoT system. I understand that the boards can be programmed with either the AT commands over UART which is probably the simplest way. Or you can erase the firmware that allows for AT commands and program directly on the STM32 chip.
I would like to try both AT commands and programming on the chip, but the product page of the module clearly states that once you erase the default firmware, you won’t be able to reflash it. Is there a binary anywhere that would allow me to put the AT command firmware back on?
I would like to be able to test out both types of programming without fear of not being able to go back. Thank you for your help!
