## Solving Sonoff 4CHpro programing issues
If you have problems to program the 4CH-pro, you might find below tips useful:
Step1) Ensure right port is set in the Arduino IDE.
Step1) TX/RX are printed correctly on the pro version => TX goes to RX PIN and RX to TX.
Step2) If you use windows7+, check in the device manager if the port is not added/removed all 2 seconds.
=> If yes then your USB port does not deliver enough ampere.
=> Moving to a Laptop might do the trick.
Step2) Reduce upload speed to 57600 in Arduino IDE.
Step3) Use an active USB HUB if your computer delivers not enough ampere
=> External power source will stabilize the 4CH-pro and you can increase upload speed back to 115200.
