I'm doing some experimentation sending a serial message ( 115200 baud rate) to ezbv4. The project sends a packet of 10 bytes every 100 mS. The packet is not always being sent every 100 mS, but very often it is not sent, as you can see in this oscillogram. (each pulse you see is the 10 byte packet) . The're correctly spaced by 100 mS , but many are missing.
CCan somebody explain what's going on ??

What are you doing with the sendserial? Are you trying to communicate with another device? If so, is there anything we can do to help?
if you want to provide details of the thing you’re trying to do, that would be easiest for us to help
I'm still experimenting to control ubtech alpha 1S servos with iotiny and ezbv4 i know your opinion about that (not enough info about protocol ,etc.). A hopeless work. However i'm going on. I saw that your plug-in sends all together, many ( 16x10-byte) messages, for 16 servos. Perhaps too many. I'm trying to send single messages, for a single servo, to see what happens. I need some tool to send perfect messages, and realized that sendserial isn't good for that. What was used in your plug-in? what can I use ?

As documented in the manual of the UB Tech servos plugin, the Send Serial (software serial) should only be used on IoTiny and never on an EZ-B v4. I recommend reading the manual for the UB tech servos in entirety.
