During the start-up all the mounted sensors run a self test. If either of these test fail it will cause the 5 red blinks. It is possible to see exactly what failed by connecting to the Crazyflie with the cf-client and open up the console tab. | During the start-up all the mounted sensors run a self test.

- | The picture shows the console tab with no errors but when you have an error it might say e.g //MPU6050: Self test acc Y [FAIL]. low: 0.300000, high: 0.949999, measured: 0.0.// This example means that the accelerometer Y axis didn't pass the self test and is probably defective. It is possible to get this error also if the Crazyflie is moved to much during the self test so try putting it on a sable surface before you power it on. | + | The picture shows the console tab with no errors but when you have an error it might say e.g //MPU6050: Self test acc Y [FAIL]. low: 0.300000, high: 0.949999, measured: 0.0.// This example means that the accelerometer Y axis didn't pass the self test and is probably defective.

E.g. use a table edge to tap/bang it against, and tap/bang the rounded corners of the PCB (where the LEDs are). This could in theory release the accelerometer lock-up. |
If anything of the above didn't fix it you probably have a broken sensor and the sensor needs to be replaced. Contact [[https:// | If anything of the above didn't fix it you probably have a broken sensor and the sensor needs to be replaced. Contact [[https:// | ||

- | When the PCB arm breaks it breaks it almost always break as in the picture. Since there is a bit of it left it can be used to fix it. | + | When the PCB arm breaks it almost always break as in the picture. Since there is a bit of it left it can be used to fix it. |
