Hello! I have the following setup: Port 0 : IoTiny configured in AP Mode as master Port 1: Arduino via USB Port 2: IoTiny configured in Client Mode connected to Mater IoTiny
In windows I can successfully connect to the AP Mode IoTiny. In ARC I can successfully connect to all three ports. I can send 1 servo command via the IoTinys, but then both automatically disconnect immediately after.
- I have tried changing the IP addresses.
- I have lowered the battery monitor setpoints to 4 V. The Tiny's are running off a power supply at 5V.
Is there something else I should try?

Your diagnostic log shows the voltage to be 4 volts. That’s not enough voltage. I believe ezrobot has a data sheet for that iotiny. Otherwise Jeremie can chime in
generally 7.4v lipo is recommended
by not providing enough voltage, the iotiny is browning out and rebooting when it tries to use wifi and audio and other peripherals when you connect
I found the data sheet for you: https://www.ez-robot.com/learn-robotics-ezb-smart-robot-controller-and-iotiny-datasheet.html
OK thank you, figured it had to do with power supply. I measured across the wires feeding into the tiny and it read 5V, but it must drop to 4 when I have the other components running as well. I will have a step up transformer at 12V that should be OK according to the data sheet.
Yeah, around 4.5V is the bare minimum.
I'm curious though, I've never tried connecting one IoTiny to another. I've heard of people doing this, but it doesn't make sense in my mind. Can ARC communicate through an IoTiny like that?
If I have more than 1 I just use client mode for all the IoTiny's and connect them all to a router.
...Well never mind, I just tried it and it works. Even old dogs can learn new tricks sometimes

I now have 6 Volts at the terminals to the IoTiny's and still they are cutting out. Also the speakers are screaming that the battery is low. The data sheet shows a minimum of 4.5, so you would think 6 Volts would be fine. Do I need to boost to 7.4 or is something else afoot?
Ah yes, you are likely unaware of the Battery monitor override that’s available in the connection skill. The IoTinys won’t respond when the low voltage warning is active, as this saves LiPo batteries.
Click the 3 dots on the connection skill to get into the Settings, then click the battery monitor tab and click the checkbox to enable the Battery monitor override then uncheck the Enable battery monitor checkboxes for all the EZBs or just lower the min voltage number to 4 or 5 (volts).
