Thanks for your help on the code updating, going back to the screen helped. The BLE TX is working now with the list, but I’m still debugging on the “Receive Byte Array” array in this post: > [@Why does BLE Receive String work, and BLE Receive Byte Array not work](https://community.thunkable.com/t/why-does-ble-receive-string-work-and-ble-receive-byte-array-not-work/1831529): > > So I’ve faced some issues with a BLE read, and here is the best summary I have: “Receive String” works on a READ characteristic “Receive Byte Array” returns on error on the exact same characteristic. Here is my case, I can connect to a BLE device, and then read on a button click. Using a counter, I can alternative between the two reads. The read string version returns the data, but the Receive Byte array always flags an error. Ultimately, I need the Read Byte Array for my application, but I… --- _[View the full topic](https://community.thunkable.com/t/resolved-error-in-transmit-receive-on-ble/1827667)._
