Sending Files #1

Hi,

I found your repository when looking for sending files over LoRa.

lucky for me I had a not so different idea of sending it as chunks with 2 last bytes as "extra" CRC-ish validation

but im finding it still to come with a few solutions on this.

could I write you over telegram to chat a bit more about this specifically?

What in particular are you interested in ? There are reasonable long descriptions of how the file\image transfer works on the blog.

Dont do telegram.

I've seen both ways:

send file from ESP32-LoRa_1 to ESP32_LoRa_2.

and also send file from ESP32-LoRa_1 to PC.

both seems to use a sketch that loads the file and separate them into chunks and sends the header to warn about new file creation in Rx module, right?

There are various packet headers used to control the transfer process, they are listed in the library examples \DateTransfer folder.

There is an optional program for the LoRa device receiving the file\image that allows you to transfer it to a folder on a PC via the serial interface.
