I investigated Dorji's UART friendly DBM01 BLE (Bluetooth Low Energy) modules quite some time back,& am overdue to relook at these & also update with other such offerings.
Dorji's DBM01 seemed to be a variation on Jinan Huamao Tech's (hence "HM") HM-10 or smaller HM-11, based around TI's CC2540/41 SoC (System on a Chip). Nordic offer similar based upon their nRF51822. IOS & Android phones (from 4.3 on) handle BLE nicely,with diverse apps. increasingly available, especially for sports & medical BLE devices.
HM-10/11 - 17 now look increasingly popular (& cloned ...) & there's also a dual mode HM-12 that may give greater versatility. Module prices seem in the US$7 -$10 range for most offerings, although FastTech have the HC-16 & smaller HM-17 at ~US$5 globally freight free.
Compared with classic BT the much lower current drain & improved range of BLE tempts,& PICAXEable wireless links may well be worth exploring. Although BLE modules offer a great swag of connections & "AT" configuration, for simple work just 4 classic serial wires (TXD,RXD, VCC & GND) may do - see pictures.
Any up to date experiences & insights to share? I'll post my own of course too. Stan.
