Just got the servo pack add-on for my son’s mBot. He’s 6 and uses mBlockly to program the mBot. Needed to upgrade mBlockly to the newest version on iTunes to get the servo functions. Did that and the servo and ultrasonic sensor worked great. Then we added the LED board. Commands for that board were not working. So I downloaded the newest mBlock, connected the mBot to my PC, and updated the firmware. Now the LED board is working perfectly, but the ultrasonic sensor does absolutely nothing. I’ve tried all the ports, plugging it in very firmly, updated the firmware again followed by reset default program. Just can’t get the sensor to trigger anything now. Is there a problem with the newest firmware and the ultrasonic sensor? Is there an older firmware I can go back to?
New firmware broke the ultrasonic function in mBlockly

Hi jonkhill,
Is there a red LED lit up on the sensor module when it was powered on? Does the Ultrasonic sensor works in wall avoidance mode when you reset its default program back?
If it still doesn’t work, please kindly refer to each step one by one in this document to check again.14. The example program to test if the Ultrasonic module is working properly.docx.zip (20.1 KB)
