When using the BL600, how many peripheral devices may it connect to at once?

Answer

Laird's BL600 BLE module only supports Peripheral mode. When loaded with peripheral firmware, only one connection can be made at a time. If Central mode is needed, then you will need the part number BL620 with Central firmware load. The hardware between both part number series is the same-- the only difference is in the firmware load. When loaded with Central role firmware, the BL620 currently supports up to 4 simultaneous connections.
