Sending and receiving specific AT Commands for SPIFriend

[mrnoisytiger]

I'm looking to send specific AT commands to the Bluefruit SPI Chip, specifically the AT+FACTORYRESET in a custom keycode. Is there a way that's recommended to do this?

In tmk_core/protocol/lufa/adafruit_ble.cpp, there is:

bool at_command_P(const char *cmd, char *resp, uint16_t resplen, bool verbose) {
    auto cmdbuf = (char *)alloca(strlen_P(cmd) + 1);
    strcpy_P(cmdbuf, cmd);
    return at_command(cmdbuf, resp, resplen, verbose);
}

bool adafruit_ble_enable_keyboard(void) {
    char resbuf[128];

    if (!state.initialized && !ble_init()) {
        return false;
    }

    state.configured = false;

    // Disable command echo
    static const char kEcho[] PROGMEM = "ATE=0";
    // Make the advertised name match the keyboard
    static const char kGapDevName[] PROGMEM = "AT+GAPDEVNAME=" STR(PRODUCT);
    // Turn on keyboard support
    static const char kHidEnOn[] PROGMEM = "AT+BLEHIDEN=1";

    // Adjust intervals to improve latency.  This causes the "central"
    // system (computer/tablet) to poll us every 10-30 ms.  We can't
    // set a smaller value than 10ms, and 30ms seems to be the natural
    // processing time on my macbook.  Keeping it constrained to that
    // feels reasonable to type to.
    static const char kGapIntervals[] PROGMEM = "AT+GAPINTERVALS=10,30,,";

    // Reset the device so that it picks up the above changes
    static const char kATZ[] PROGMEM = "ATZ";

    // Turn down the power level a bit
    static const char  kPower[] PROGMEM             = "AT+BLEPOWERLEVEL=-12";
    static PGM_P const configure_commands[] PROGMEM = {
        kEcho, kGapIntervals, kGapDevName, kHidEnOn, kPower, kATZ,
    };

...

I effectively want to mimic the static const char kXXXp[ PROGMEM = "ATCOMMAND" lines but inside of a custom keycode.

My initial intuition is that I can simply create a function that sets a char array, then runs the at_command_p() function to send it:

char resbuf[48]
static const char kFRST[] PROGMEM = "AT+FACTORYRESET"
at_command_p(kFRST, resbuf, sizeof(resbuf))
