• Then sorry for the noise. You did not link that tutorial before.

    I was guessing you think HC-05 is BLE and expect to find it via Web IDE when clicking bluetooth. Still, everything in that tutorial and what I said applies.

    There is also similar tutorial for adding BLE module to original Espruino here https://www.espruino.com/Bluetooth+BLE

    Currently if price is same, getting two HM-10 may be better than getting two HC-05 to connect them to each other and/or if you also want to connect to it from nrf5x devices. Also BLE version may draw less power.

    However in your case it is true that BLE version (HM-10) would not work directly with WebIDE as described there so using HC-05 makes better sense.

    In theory HM-10 could work with WebIDE as direct BLE connection. However HM-10 does not implement Nordic BLE UART protocol. It could be added as all those BLE serial protocols are similar so just using diferent service guids may work. When checking now the ble_uart and ble_simple_uart modules described in https://www.espruino.com/BLE+UART can also do only nordic uart so adding HM-10 there could be useful too.

  • don't worry for the noise - however I still do not know how to proceed.

    In principle, the Mac should ask me whether I'd like to couple the HC-05 - but it doesn't.
