Im using basic AT command in ADA14531. I used AT+GAPCONNECT to connect to certain ble module. however, i cannot set it as central ble or master BLE to allow it to scan for ther ble. do i have to use binary code or what?
Hi SUFI,
Thank you for posting your questions online.
1, The default mode is peripheral mode.
2, Please send following CMDs to switch to central and scan for peripherals.
3, User manual: 9. AT Commands — DA145XX Tutorial SDK Getting started (renesas.com)
Thanks

Hurm yes i did that. ok like this there are 2 ble lets say A and B. i assigned the A as central and ask it to connect with B. the question is, from the connection, can i assign B onwards to become the 2nd central ble to scan for C and D lets say. means like it will become continuous connection from A to B . then B scan for others. if this is not possible, does binary mode support this?
Hi again. May i ask is it possible to use AT command to allow the assignation of BLE to becomes a central / master instead of peripheral after we connected to it?
Sorry, it is not possible to keep connection than switch to central.
Device only can work as one role central or peripheral. So, A can sent a CMD to B to switch to central, but can't keep connection, because they are all central no one broadcast.
BR,
Sorry, there is not possible to realize this feature on BLE. As we talked device only can play one role in the connection.
understood. but may i know is it possible to do it through binary mode
No, Binary mode is a service which based on the connection not a role like central or peripheral.
