What steps will reproduce the problem?
1.I was doing initial setup for my Quad using Mission Planner 1.2.91 build 1.1.5107.18644
2.I played with something in Terminal section then the connection between APM 2.6 and my Laptop using USB cable got failed and says after 30 seconds timeout '‘No heartbeat packets received’'
3.Then i installed new update of Mission Planner but still the same problem.
What version of the product are you using? On what operating system?
Mission Planner 1.2.91 build 1.1.5107.18644 and APM 2.6
I also had this issue…
I could upload the firmware without issue… but trying to connect in Mission Planner would try but time out (Mavlink?) with ‘‘No heartbeat packets received’’
for me it was because i had not defined my board type in APM_Config
1.I was doing initial setup for my Quad using Mission Planner 1.3.70 build 1.3.7277.34800
2.I played with something in Terminal section then the connection between APM 2.6 and my Laptop using USB cable got failed and says after 30 seconds timeout ‘‘No heartbeat packets received’’
