Telink 8258 Dongle Specification 2 Pin Connection Guide 2.1 Supply power There are two methods supported to supply power for the TLSR8258 Dongle. 1) Supply power via battery: Connect PIN1 and PIN3 of J6 with GND and 3.3V of power, respectively. Note: There is no need to connect any header with jumper cap. Make sure the cap is removed from J8. 2) Supply power via USB interface: Make sure one jumper cap is connected on J8 of TLSR8258 Dongle. Connect the USB interface of the TLSR8258 Dongle with PC USB.
Telink 8258 Dongle Specification 2.2 Download firmware To download firmware into TLSR8258 Dongle, first make sure the TLSR8258 Dongle is supplied with power normally (please refer to section 2.1). Then connect J6 PIN2 (SWS) of the TLSR8258 Dongle with SWM of a burning EVK (TLSR8266BR56). Meanwhile, connect the miniUSB interface of the burning EVK with PC USB. 2 J6 Connect PIN2 with SWM of TLSR8266BR56 Figure 6 PS-19012802-E1 Connection chart to download firmware 10 Ver1.0.
Telink 8258 Dongle Specification 2.3 Test RF signal To test RF signal of TLSR8258 Dongle, first make sure the TLSR8258 Dongle is supplied with power normally (please refer to section 2.1). The J1 should be connected with a spectrum analyzer via a RF cable (supplied by Telink). Connect J1 Connect spectrum analyzer J1 Figure 7 PS-19012802-E1 Connection chart to test RF signal 11 Ver1.0.
