Imp004m wifi channel

hello, currently my imp004m can only connect to wifi channel 0-11
but i also need to connect to channel 12-13.
can i enable the ch12-13 by software? or it’s hardware restriction?

It’s a software restriction; you can set the country code during the blessing process. See imp.setcountry() | Dev Center

…but note this is only for commercial customers. FCC rules make it hard to sell a generic module with ch1-13 support in the US, so by default the setting is for US (ch1-11)
