I've found that:
char *protocolMyMessage2Serial(const MyMessage &message)
{
(void)snprintf_P(_fmtBuffer, (uint8_t)MY_GATEWAY_MAX_SEND_LENGTH,
PSTR("%" PRIu8 ";%" PRIu8 ";%" PRIu8 ";%" PRIu8 ";%" PRIu8 ";%s\n"), message.getSender(),
message.getSensor(), message.getCommand(), message.isEcho(), message.getType(),
message.getString(_convBuffer));
return _fmtBuffer;
}
We put in the print "message.getEcho()", but this isn't echoed message.
I think we should put "message.getRequestEcho()" here.
@TheoL there are two pull requests adding support for newer versions.
One is guaranteed to break again.
One should not break in the future, but will instead break all existing sketches.
I’m sure a third option would be welcome if you write the code and submit.
