How to use callbacks with this package?

[deadprogram]

Does this package currently support callbacks?

For example, I would like to use https://github.com/sago35/go-erpcgen/blob/main/rtl8720dn/rpc.go#L2701 in the same way it is used here https://github.com/Seeed-Studio/Seeed_Arduino_rpcUnified/blob/master/examples/ble_client/ble_client.ino#L50 or something similar?

@deadprogram No, it is not supported at the moment.

Currently, the code generated with go-erpcgen does not work with BLE. The reasons for this are as follows. First, we need to address this part, but when I tried in the past, I couldn't complete it all the way.

• The code generated with go-erpcgen is designed to always send and wait for reception from WioTerminal. However, in the case of BLE code, the transmission may start from RTL instead of WioTerminal.

The relevant posts are as follows.

@sago35 so for example, we would need to do something like this?

• client makes rpc call to start scanning e.g. rpc_le_scan_start()
• periodic call to https://github.com/sago35/go-erpcgen/blob/main/rtl8720dn/rpc_util.go#L68 to check if any data sent from rtl8720dn
• parse that data, and check for any BLE messages
• keep calling read() periodically until client calls rpc_le_scan_stop()

Does that sound correct?
