Most Apps and Examples using BLE demonstrate how to receive data but my App only Transmits.
I have an RN4871 Module connected to a micro that sets it all up for transparent uart mode.
I rename it as "Temp". Over the past few years, I have tried BLE2 and can scan, connect to the device, and can Transmit Commands (simple "g"CRLF) to it up to 8 times.
After that, the Manager_writecomplete event tells me it thinks a command has been sent but the micro never sees a command. (I have verified this by attaching an FTDI serial to usb cable to monitor the incoming (logic level) RxData from the RN4871.
After the BTLE gets stuck like this, I can shut down the App, restart, reconnect and can't get the RN4871 to receive anything. Only after power cycling the RN4871, can it receive any commands (although no more than 8).
I can run microchip smart data or Kai Morich's Serial Bluetooth Terminal and send commands and receive them all day.
Also, I can use BleExtEx and have no...
