Hi to All.
Question is what’s the resistor OM we should use.
At “Hardware Design” we can read:
“3.7.2. W_DISABLE_N Signal*
EP06 module provides a W_DISABLE_N signal to disable or enable the RF function (not include GNSS)
by hardware method or software method. Hardware method can be controlled by W_DISABLE_N signal,
this function is disabled by default, and AT+QCFG=“airplanecontrol”,1 can be used to enable this
function. The details of W_DIABLE_N signal function is as follows:
High Lever | RF enabled | Normal mode
Low Level | RF disable | Airplane mode”
“1) When W_DISABLE_N control function is enabled, RF function can be enabled by pulling
W_DISBLE_N to high level and executing AT+CFUN=1.”
All this give us info that pull-up should not work is we not enable this feature.
But who know’s if it’s not enable from AliExpress seller… who in 90% sell that QDL state the cards.
@arni - He receive a new firmware, he do QFlash and see the finall PASS and after his EP06-E is detect correcly but all COM-s are flapping. He add link to his case upper at your post.
Then we know that are two ways
- some firmware
- pull-up resistor
We should not write about any resistors, that modems should be a production, good to ent-user who should just use it and not add resistors.
