Recommendation for a Bluetooth device

Post by sirmichael »

I'm trying to add Bluetooth to an existing Arduino MEGA project and trying to find a device that will communicate with a radio, an ICOM IC-705.

The Bluetooth specifications for this radio are:
••Version: Bluetooth Version 4.2
••Transmission Output: Class 2
••Profile: HFP, HSP, SPP, GATT (Serial) over LE

••The maximum number of paired Bluetooth devices:
5 devices
Either headsets or data devices are maximum 4 devices, and the combination is 5 devices in total.

If it helps, the radio uses a Hosiden HRM1016 device for the Bluetooth comms.

I've successfully connected an HC-05 (BT version 2.0), but the comms is intermittent and very slow. I've also connected an ESP32 WROOM (BT Version 5.0) which works superbly, but I can't use this device because it's not compatible with my project (and WAY too much work to rebuild).

I purchased an HM-10 (BT Version 4.0) and an HM-18 (BT Version 5.0) but neither of these are discovered by the IC-705 radio. Apparently, there is a protocol that is not supported that is compatible with the radio. They do BOTH connect to my Android phone.

Any suggestions of an Adafruit device that I can integrate into my project, similar to the HC-05 (TX/RX comms) that would connect with this radio?
