I have an
Arduino nano and a HM-13 bluetooth module and I’m trying to discover/scan available devices (ex:MAC ADDRESSES) in the room but there is nothing on the DATASHEET about this.
I search the
AT command to send at Bluetooth module.
Documentation : https://seeeddoc.github.io/BLE-dual-Bee_v1.0/
Code : <LINK_TEXT text=“https://github.com/Seeed-Studio/HM_13_S … _13_SW.ino”>https://github.com/Seeed-Studio/HM_13_SW/blob/master/HM_13_SW.ino</LINK_TEXT>
Thank you !
Have you tried to set Master role and then do the scan? thanks.
I am well in master role and the module is set visible; then I restart the module to take effect.
My Buetooth firmware version is v316.
The latest datasheet version for my module is at this link : http://www.huamaosoft.com/bluetoothdual_en.zip
The AT commands start at the page 16 of the file bluetoothdual_en.pdf.
But the documentation of seeedstudio is not bad : https://seeeddoc.github.io/BLE-dual-Bee_v1.0/
But impossible to find the AT command to scan available devices…
Thank you for your help
when we use HM-13 as master role, we have to close all the ble devices around, turn on the one to be connected. the hm-13 will automatically scan and connect to it. it does not have AT commands for the scan ble devices id functions.
you can choose HM-11, it has the AT commands to connect specific ble devices. thanks.
OK, too bad…
Thank you again for your help Bill !
