i am working on a project that need to control a device via ble uart. i am using generic ble nodes on node red. my flow is as follows: timestamp -> function where i send the buffer as msg.payload -> generic-ble -> debug. but i can't get the result that i want. whatever the value i push in, i get the same result from the debug

I don't think this is the right forum to ask this question. Try a Node Red forum?
