That's odd. 

1) The first thing that springs to mind is that you're not
setting the transmit carrier. This is necx so you could try:

ir-ctl -c 38400 -stv.ir 

Note this should be almost equivalent:

ir-ctl -S necx:0x70702

This does not repeat it for four times, but this does:

ir-ctl -S necx:0x70702 -S necx:0x70702 -S necx:0x70702 -S necx:0x70702

2) What raspberry pi OS and hardware are you using?

3) Since you're using gpio-ir-tx you need a raspberry pi which isn't ancient.
Beter to use pwm-ir-tx on a recent kernel.

4) Can you do ir-ctl -r in one window and ir-ctl -s in another? Is the output
what you expect?

The lirc daemon is not used at all in your way of doing this. Which makes
it off-topic for this list.
