Connection HM-10 to Nano 33 IOT using Bluetooth

Projects General Guidance
1

I have a two Arduino setup where I have an Uno connected with a HM-10 and then an Arduino Nano 33 IOT where I am using the internal BLE chip. I want to connect the HM-10 and internal BLE on the nano together using Bluetooth and then send data from the Nano to the HM-10.

Currently I have got to the point where I can scan for the HM-10 from the nano and isolate its UUID, but then when I try to connect to it the connection fails. I am able to easily connect to the HM-10 using my phone, but trying to connect using the nano doesn't work.

How is the Nano powered? When it sends BT it needs much more current then at listening only.
